Ok, found some limits on basic ocing this 1070. So I am now wanting to look more into the "Power Curves" some have mentioned for this card. Where can I find a guide on this?

Thanks!
I had something like this up when 3dmark froze and I was unable to get it to completely shot down so I had to restart my PC....

download aida64, there you can see a complete SPD memory timings & voltage
Write everything on the paper.

go to bios
set manually your rated DRAM voltage that require to run at 2400 according to your RAM (1.65V or 1.5V?)
set memory speed into 2400
input every timings you got there into bios (Timing's name could be slightly different on your bios)

Example on aida64 mine looks:
@ 1200 MHZ 11-13-13-35 (CL-RCD-RP-RAS) / 48-314-3-8-18-10-10-31-13 (RC-RFC-CR-RRD-WR-WTR-RTP-FAW-WCL)
In my case I need to lower TRRD & CWL
TRRD 8 lower to 7
CWL 13 lower to 12

Boom it booted instantly with 2400mhz speed (@1200mhz in cpuz/PC19200)
In my case i dont even need to increase VCCSA/VCCIO, my VCCSA/VCCIO still at default voltages running with 2400.
But I dont know in your case.

Hmm alright that seems easy enough thanks for the explanation. In the worst case when I can't boot anymore I would just do a CMOS reset right?

Dual channel will give you better performance than single channel

I have never used an Asrock board so I am not familiar with the specific quirks. The VCCIO voltage in the bios is the one that helps fortify the memory controller. Increasing that from 1.05 to 1.1 may help you get the ram running faster. It also helps improve stability of the PCIe controller for overclocking GPUs.

You should be able to increase bclk to 103 - 104mhz and not change anything else. That will give you 4532Mhz on the cpu and 2060Mhz memory at 103BCLK. If it wont boot, try dropping the multiplier to 43 and trying again. x44 multi on those chips is not right at the ragged edge so I would be surprised if it does have too many problems. If it starts giving whea BSOD, increase vcore voltage slightly.

I have been wanting to upgrade mine too. The fact that my system it now makes PSUs go bang when you turn it on has forced the matter. I have been really considering a Ryzen system. I was originally thinking R7 but now I think an R5 6 core would be a better buy for my needs. The current Intel x99 broadwell-e products are now overpriced for the performance you can get out of them and I think that 4 core chips, even though they offer better single core performance, will be pushed aside by 6 core chips in the next year anyway.

I know I looked extensively into the issue but I was and still am afraid to actually pull the CPU out of the socket now in fear to make the problem worse as I have no idea how the state of the pins is and I rather have a working Single Channel system than trying to fix it and having to buy a new system right now.

Thanks for the tip, first I'll try what Zipper17 suggested though, it sounds like the problem is quite similar to mine. Interesting on the baseclock though, I'll definitely try that, I have more than enough experience with Ivy Bridge stability-testing by now.

That doesn't sound good on your system alright, I hope it still works for you for a while. I thought about Ryzen too but I'm not sure if they are for me, I definitely want a improvement on IPC single-clock performance along with more cores and from what I read AMD made huge strides there but in the end that's an area where Intel is still better at. Is Ryzen beating Ivy Bridge on IPC performance? I really hope Intel is forced to drop prices on their six-cores, around 300€ by the end of the year and I would bite, although I doubt that will happen.
 

I wasn't talking about the CPU socket having dust in it. I assume the CPU went in when the board was new so no way for the dust to get in there. I was talking about the memory slots themselves.

 

If you are going to make changes in the bios. If you haven't done it yet, save your current settings as a profile. if things mess up, you can just reload the original settings.

 

My system is dead. the board has formed a short circuit for some reason. It has now killed 4 platinum PSUs so I wont try again without a different motherboard in it. If i can find a cheap used z68 or z77 board, i might just swap the CPU, memory and cooler over and run that for a while. Fingers crossed that the board dying did not fry my CPU and GPU.

 

I am torn with Ryzen. I did own an AMD pc about 15 years ago and the performance was better than Intel in those days. The problem then was windows would add a feature that the AMD chip would not support so It always felt like a compromise. I am worried that it may be the same now. The Ryzen platform really needs to mature a bit more but I do get my jollies solving Tech problems. Ryzens problem currently is memory throughput limitations that are impacting the gaming performance

 

Ryzen actually performs better than the equivalent Intel CPU in areas that don't hammer the memory sub system. They are having similar challenges getting DDR4 working well that X99 had when it was launched. Latency is a bit high and some people are having trouble getting memory trained to run at 3200Mhz but that is more about the immaturity of the platform bios revisions. There are guys with 3600Mhz ram running and memory latency is down from 100ns at launch to 60ns but still another 20ns to go to be comparable with Intel memory latency.

 

The Ryzen SOC design architecture is much more sensitive to memory speed than the Intel architecture so It will take it a while but I am sure that performance will improve further. A new microcode/bios is due out soon and that is supposed to improve memory support significantly, hopefully allowing tighter Ram timings. I'm sure that It will get there eventually. I was planning on waiting for it to mature another couple of months before deciding to jump in or not but this hardware failure may have forced my hand.

You mean the voltage curve?

 

The best place to get educated on curves is probably reading back through this thread. I have written a few mini tutorials, most recently the other day.

 

There is no official documentation that I know of.

 

What model card are you running?

I need to update my profile with this card.
It is an EVGA GTX 1070 SC ACX 3.0


I am waiting to order a water block for this card but the ACX 3,0 does a great job keeping it cool, much better than the ACX 2.0 did on my 980.

Will a waterblock improve OC capability like it did for the 900 series and earlier cards?

EDIT: Where are the LED controls for the cards now in Geforce Experience?

You are right. It is under performing in gaming workloads and in other workloads that require high memory throughput such as 7zip compression. Memory support is improving every day, the deficit is progressively being reduced to an equivalent Intel platform like the 6900K.

 

For some reason, the media like to avoid mentioning the combined score that is the most telling part of the firestrike benchmark that shows the bottleneck in the uncore/Infinity Fabric part of the Ryzen chip. Then again everything about the Ryzen launch has been a bit strange with most of the industry having a suspension of common sense.

 

The Ryzen CPU is a System on a chip, The processor is made up of two 4 core modules that each contain its own cache memory. The Infinity fabric is effectively a network that connects the two 4 core modules to the memory controller and the I/O controller that contains the PCIe Controller, The on chip Sata and the USB controller that are built into the Ryzen Chip. The Infinity fabric clock speed is tied to the memory frequency and like any network the performance is effected by latency. Right now that is quite high but improving. The end result though, is that gaming workloads and things like 7zip compression, that need lots of throughput between the cores and the GPU tend to be under performing because the higher latencies make the cpu sit waiting for data to arrive. The CPU actually works really well when it does have the data to use though.

 

In single core performance, A 7700K will always win. It is clocked 25% faster and has a higher IPC. Ryzen IPC pretty much matches Broadwell E in single core tasks but tends to be more efficient in multi core workloads. If you compare a 7700K, Ryzen R7 and an i7-6900K in cinebench, you can see how they all relate to each other in pure processing. Ryzen will win in most multithreaded tasks unless the infinity Fabric is heavily loaded like when a AAA game is being run.  

 

If gaming is the only thing that you really do, a kaby lake is probably a better buy right now.

That makes it easy then.

 

Personally I like After Burner better than Precision XOC If you want to play with the curves. The controls are more fine grained.

 

For you though, Precision gives you a handy tool that can help get you close to the best curve for your card. The auto overclock tool that Precision has for EVGA cards doesn't actually work that well for overclocking the card but what it is pretty good at doing is getting you close to the best curve for your card. It will show you the areas of the curve that overclock better than the other parts. So what you do is run the utility and scan each point between say 50 and 150 with 12.5mhz steps. When it is finished, close precision XOC and then open Afterburner and that curve window. You can save that curve that Precision created and then tweak the points to get it stable.

 

You should probably drop each point down by 12-25 mhz and then see if it will run stable. You can then try adjusting each point one at a time starting at the highest point and work your way down the curve staying reasonably close to the curve that Precision found for you. If there is a dip in the curve, keep the dip in that area because those points dont overclock as well.

 

A Water block will help get clocks slightly higher and keep them a bit higher and more stable. You wont actually gain that much extra performance though.

 

LED controls are now in the manufacturers software. Precision XOC has them for EVGA.
