Does anyone know a reliable memory test ?

Memory that is running to high will show artifacts in Firestrike and games. If the core is to high it will lock up, and crash the driver and recover it.

Try for 2250 the max. And run through GTAV with a lot of AA. GtaV always artifacts, and crashes if the Mem is to high.

If it crashes at 2250, Try 2225. If 2225 crashes, go down 10-15Mhz until it is stable.

Depending on how high your core Mhz is, will greatly affect how high the memory will go!

For example you may find 1340 Mhz core and 2250 memory is stable.

But, 1380 Mhz core, and 2250mhz is not.

But, 1380 core and, 2200 is stable.


The RX480 is a little tricky with overclocking. But, you will know yours like the back of your hand after a while.

Memory overclocking offers a huge boost!

Find the best balance between them that is stable, with the highest Firestrike graphics score. And that will give you the best 1080P gaming performance.

I can get about 1410/2250 with mine. But, it is a one of a kind 91.5% ASIC QUALITY. Higher than 99% of all other Rx 480's, based on GPU-Z.

The highest other RX480 ASIC I've seen is 90 something %.

So, do not expect the same results. Check your own ASIC too, it's always nice to know.

As said above, personally I use games and apps that use as much VRAM as possible as well and monitor performance. If you see a decline or artifacts it's to high. Though with some AMD cards it may report actual memory error counter in monitoring but you may still be gaining performance even when you're getting a few errors that get corrected.

1,400 mhz is is in the top 90% of overclocking a RX480 on air.

AMD cards are all pre overclocked lol, even reference. Theres hardly any room left.

I had a gtx 660 OEM it ran at 864Mhz core, I overclocked it to 1635Mhz on air and its still the record in firestrike for a gtx660. It was beating gtx770's lol!

I also had a AMD 7950 it overclocked about 80Mhz! Terrible!

Ive been building computers for 13 years, those cards listed above were listed as, one of the best overclocking, and one of the worst! Obviously you see which brand did the best!

Im not a fanboy, and if AMD releases something that handles 4K better than my current solution for the same, or less money. I might just jump ship, depending on how big that boost is.


Another person claiming AMD cards don't overclock...sigh...because they had one card that didn't overclock and another that was awesome.  I can do the same thing, watch:

 

I had a GTX 670 that was a total turd, it didn't even overclock 1MHz on the core or RAM...it died shortly after I purchased it.  Compare that to my reference R9 290 that clocks over 1300/1700 when the base clocks are 947/1250; that's a 37% core overclock.  The obvious conclusion from this isolated scenario is: ALL NVIDIA CARDS DON'T OVERCLOCK!

 

:lachen:

 

You do realize that when Nvidia lists a boost clock, that is the frequency you need to compare your overclock frequency to, yes?  Just because the base clock is drastically lower, doesn't mean your overclock is enormous.  

 

It looks to me like an OEM GTX 660 had a base clock of 980 and factory boost clock of 1084... http://www.anandtech.com/show/6276/nvidia-geforce-gtx-660-review-gk106-rounds-out-the-kepler-family/17

 

Hitting 1635 MHz core clock sounds a bit far fetched when the factory boost clock is ~1.1GHz; which would make for a ~50% overclock.  I'm not saying it isn't possible because I know jack & squat collectively about GTX 660 cards....but if it is possible you probably didn't do it with air cooling.  From the looks of most review sites for GTX 660's, they peaked at around 1200.  Now I'm sure with some BIOS editing and a fantastic card you might be able to get to 13, maybe 1400...but 1600 I would have to see proof.  

 


 

Now let's see how Pascal overclocks:

 

GTX 1060 Reference 10% Overclock | Max Boost 2101: https://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_1060/29.html

 

GTX 1060 MSI Gaming X 8% Overlcock | Max Boost 2139: https://www.techpowerup.com/reviews/MSI/GTX_1060_Gaming_X/27.html

 

GTX 1060 MSI GT 9% Overclock | Max Boost 2114: https://www.techpowerup.com/reviews/MSI/GTX_1060_OC/26.html

 

GTX 1060 ASUS Strix OC 8% Overclock | Max Boost 2188: https://www.techpowerup.com/reviews/ASUS/GTX_1060_STRIX_OC/29.html

 

Are you seeing a trend here?  And if you look at all the variants of the GTX 1060's in the "Maximum Overclock Comparison" Chart in the Strix review, there isn't even 100MHz separating the FE from the best AIB card.  The gains range from 13-87 additional MHz on the AIB cards comapred to FE.  I know that TPU isn't the be all end all source, and there are obviously good and bad cards...but this paints a pretty clear picture.  

 

Where do you get your figures from?  1400 MHz is in the top 90% of 480 overclocks?  That doesn't seem to be the case from what I have experienced myself, have seen here, and viewed in the 3DMark logs/HoF.  My reference 480 stock boost clock is 1266 and it runs at 1400 MHz; 10% overclock.  Most everyone I've seen in the forums is hitting similar speeds with various forms of cooling.  Let's do the math for 8% and 9% to compare to the custom GTX 1060's.  These similar speeds would be 1367 and 1380 core clocks, respectively from 1266, on a 480 which are very likely attainable on a card with any form of proper cooling.  

 

All RX 480s aren't overclocked...that's why there are reference cards.  Or if you want to feel special, you can pay EXTRA money for a blower cooler and get a Founder's Edition card :rolleyes:

 

Yes, RX 480 AIB cards come with stock boost clocks in the low-mid 1300's and therefore have less headroom...BUT if you end up at the same final speed/performance what is the difference?  There isn't much of a difference for raw performance in either camp since you're in the same ballpark for the end result.  Nvidia just happens to do a better job of making you feel warm and fuzzy because you seemingly 'pushed' your hardware.  The biggest perk is the amount of noise the cards are going to generate doing so with the better coolers.

 

Seems to me, when you compare actual facts and figures, the overclocking abilities of this gen of mid-range GPUs is pretty equal.  

 

Overall performance is a more complex story...possibly a split depending on the title in question...DX11 likely for Nvidia and DX12/Vulkan for AMD.

It's supposed to be, but some people here are more concerned with babbling about how superior the 1060 is..it gets old quickly.  Try the RX 480/470/460 owner's thread.  

 

Run your benchmark of choice and use HWInfo.  It has a readout under the GPU section labeled 'GPU Memory Errors'.

The 480/470/460 vram clock doesnt do very well.. Most Nvidia cards vram overclocks like crazy.


Previously owned several older amd cards dating back to the hd4850,hd6850,r9-290 also had a Sapphire Nitro Fury for a short time which was complete junk also..
Currently have a rx480 with a sapphire hd7850 cooler mounted on it, I can run at 1450/2150, much more on the memory and I get errors, no matter what what voltage I use.. I also have a 90% asic quality..

I also notice the driver support is no where near the quality with amd cards compared to nvidia cards.. I've owned amd/ati cards for the last 20 years and I have to say the driver support is awful comparing to Nvidia today, and thats before of after crimson.. Wattman is complete garbage compared to any overclocking utility I've used for an nvidia card. AMD really needs to work on Wattman, its BLOATWARE...
AMD needs to start focusing on software for a change.. I think amd is spread too thin or they dont have capable software engineers at this point... The quality of nvidia products is superior at this time.. AMD stuff just seems to be patched or thrown together, overly complicated, and just doesnt function as intended, and this is coming from a hardcore ati/amd guy of over 20 years.

If this tells you anything, I had a Sapphire Fury in my main gaming machine, I sold it and since switched to a zotac 1070 amp edition, I ran it for approximately 2 months overclocked to +200core/+400mem consistently.. I've since switched to a zotac 1080amp edition and it will clock the same, but I dont have a need to overclock it..

The same very same software that you HAVE to use with NV cards you CAN use with AMD cards to OC. So in that department AMD is offering more and has OC in the driver GUI where as NV has decided a decade ago to remove it and while hacks worked a while to add it back it is since long gone.
Drivers work fine for me on both AMD and NV, each having their own quirks that persist but only comes to mind the NV latency.
Other software? Raptr? GFE? ... all garbageware, don't even install, try it once, see how bad it is and uninstall it to never install it back again.

The way AMD has OC now is IMHO better, can defined voltage/clock pairs that are hard set. Where as NV has this overboost 3.0 now that does what ever the hell it wants based on temperatures and other magic things so there is no way to set a hard max limit nor guarantee locked voltage/clock steps, it does provide NV a boost in performance in reviews and general use for people who do not OC as it automatically raises clocks above boost. But the moment one wants to OC that OB3.0 is a major PITA.

Most of the AMD and NV AIBs cheaped out to save on production costs of the new 14/16nm GPUs, especially the mainstream <$350 cards, insufficient way too optimistic coolers, underpowered VRMs, ... of course this hurts AMD way more than NV since it needs more power and dissipates more power.

There are still wide variances in quality of produced chips, up to 10% clock difference in OC on NV. Hard to tell for AMD since most of those cards are temperature and power limited but it may be up to 10% as well. As such you can have Pascal at 2.0GHz vs 2.2GHz and P10 at 1350MHz vs 1485MHz. I think the max usually seen on water for P10 is about 1460MHz, so maybe less than 10% or those bad chips are already filtered into 470s and 4GB versions...

I just picked up the Asus Strix RX 480 OC from Jet.com. I received a single use 30% coupon code from them so I only ended up paying $212 for it. To my surprise it actually came from Newegg. It was in a Newegg box with a Newegg invoice.

So far so good here. The card appears to be fully functional with no issues thus far. No coil whine, no odd fan noises, no memory errors. It appears to be extremely well built too. This thing is solid, heavy, and stays straight as an arrow in my iTX motherboard. I am using it in a Fractal Design Define Nano S case and it is powered by a Corsair SF600 PSU. It replaced the XFX RX 480 GTR Black Edition which replaced a reference model so I have those to compare to.

I am going to be putting it through the paces today, see what it can do. I will update my overclocking experience later.


PS: I was originally going to get a GTX 1060, however, I ended up picking up a LG 29UM68-P from Amazon for $200! This is a 29" 2560x1080 IPS 5ms 75hz FreeSync(40hz-75hz) Display. In my opinion, the RX 480 paired to a FreeSync monitor is "better" than a GTX 1060 and a regular monitor. (G-Sync monitors are nice but overpriced, again, in my opinion)

I've owned ati/amd gpus and processors for around 20yrs.. This recent string of amd cards are junk compared to the ati/amd gpus of old.. Not the same company at this point, I think of cheap chinese quality when I think of amd now.

As far as Wattman, I've renamed it Crashman, every time you try to open it to make adjustments it crashes, and its a well known problem that replicates.. Amd has known about it since launch as I reported it and AMD is well aware of the problem..

I couldnt tell a difference running freesync with the Fury.. I have a 32" Crossover 2560x1440 75hz monitor with freesync, or adaptive sync and I couldnt tell a difference with it on or off.. I since swapped from a Sapphire Fury to a Zotac 1080amp and I left "freesync" on the monitor, yet the "adaptive sync" must be working with the 1080 because I get no tearing at over 130fps

Quoting myself here.

I thought I would provide an update on the Asus Strix RX 480. At first glance, it is an awesome card! I thought it was the best RX 480 to date. I purchased it with the intention of selling my XFX RX 480 GTR Black Edition to my friend. Well, luckily he didn't buy it from me yet, because I am keeping it! What I intended to be a small upgrade ended up being a downgrade.

The build quality on the Strix is pretty good, but the XFX is better. The back plate is twice as thick, the heatsink is nicer with thicker fins, and the fans are much quieter. Even though the Strix is larger than the GTR, the GTR felt slightly heavier. The thermal performance was slightly better (1-2 degress) on the XFX despite the Strix having a slightly larger heatsink, 3 fans, and being much louder. Asus included extra features on the Strix like fancy RGB lighting and 2 case fan headers at the expense of overall build quality and materials.

I am well aware that not all silicone is equal, but I can hold 1400mhz @ 1175mv on the XFX stress testing all day long. The Strix was still unstable at 1400mhz with 1225mv. I also spoke too soon on the coil whine. Before I knew it, the Strix was exhibiting the worst coil whine I have ever heard, period. The XFX has yet to exhibit any.

The Strix just got dropped off at FedEx.

Whyd you drop it off at fedex? returning it? Why not return the strix and get another xfx card and crossfire?
