Hi everyone, I have a couple quick questions:

I'm trying to get the highest possible stable OC from my 8350. Right now I'm trying to get 4.5GHz stable, but so far I've had to bring the voltage up to 1.440v according to CPUz (I'm currently running Prime95 small FFT to test it). Does this seem a bit high, or is that normal for these chips?

Second is about temps. According to the Core Temp reading (same as HW Monitor "package" temp) I'm in the low 60s at these settings. Am I correct in thinking this is the temp I need to keep under 62c? My other temps are TMPIN0=26c, TMPIN1=54c, and TMPIN2=75c.

Are these temps and voltages about normal for an 8350 on air? If the temps are correct, its looking like my max OC might be 4.4GHz, which seems a bit low, but I have zero experience with FX, so any help would be very much appreciated.

What is your CPU voltage under load?
1.44v is pretty high for 4.5Ghz if that's under load. (unless you have a really high vid, but then you should be getting really good temps as well)

Could you post a screenshot running IBT 10 runs on standard. Please include HWMonitor in the screenshot, showing the CPU Temp, voltages and Package Temp.

Oh I see. I've never seen an option like that in CCC.
post #14303 of 67492
Yesterday my rig shut off in the middle of use again. This was /AFTER/ I turned off 'Hardware Thermal Control' (ie. throttling back) in the BIOS. So if it wasn't something the board was doing electively, I figured I had to admit defeat and scale back the overclock a bit to 4.8 Ghz. D:

We'll see if this is more stable.

Your source for FX steamroller in 2014? That last public information from AMD is FX steamroller in 4th quarter 2013. They have not announced any delay to 2014. Be careful of spreading uncomfirmed information. It is purely conjecture and causes problems.

Thanks for your help. Hopefully I set this up right, I've never used IBT...

After the test (shows max temps):


These tests ran cooler than Prime (possibly due to the shorter run time).

It would appear that you are running the non avx version of IBT. Your temps and Gflops would be higher smile.gif

tight=less, loose = higher ( numbers )
someone already went through how best to oc ( i just start where i want to be and see if it is ok... my ram is no where close.... so i just buy new ram and try again LOL ) everyone has to learn and we are here to help. please everyone dont apologize for asking. asking questions is why OCN exists !~

1.44 sounds low to me 1.45~1.46 ( in bios ) with high to ultra llc is about average.
less then 40c look at package temp ( the one core temp displays ) otherwise look at socket temp ( download hwinfo64 to see )

EDIT: hey guys im sad to inform I have reached my absolute Overclock limit on my build.. part of it is temps part of it is amperage on PSU and the rest is just need better hardware more or less graphics cards.. but hey its been fun and I learned a lot cheers.gif

this doesn't mean im leaving the thread however nor more awesome benches till I can change more My max for the 8350 was 5.15 @ 1.67v only bench stable for what its worth VID < 1.4 should be able to hit better but not bad for a high VID. Even though I lost the silicon lottery I still made it past 1.1GHz overclock

The Sabertooth board is a great board and haven't had issues with it for the most part.. Crucial Ballistix Great RAM... however if I Loosen the timings I won't see much improvement of scores.. This was a great test for beginning of watercooling and im glad I made the choice Custom is the way to go thumb.gif

I did end up buying a Thermaltake slot fan that drastically reduced my top card from over heating.. Im sure I could push the cards a little bit my but I must mod the BIOS of one first.. Once I do that I run a few more benches

I have seen something odd the new 3dmark was using my top card for primary physics even though through the control panel I had it set to use #2.. Just thought to let you guys know so you can play around with some more settings to get better scores.

Oh if anyone has any questions of what I have done or what all my build is like feel free to ask..
Drop timings one by one in fashion of 9-9-9-27 to 8-9-9-27 and so forth until unstable. then raise one to make stable. once you have your timings tight up the frequency till unstable. then loosen the timings on by one till stable. Repeat.. You will hit a point that its not worth loosening timings for frequency or not able to be stable.

once you get the hang of how your ram feels then you can up the voltage depending on how much further you want to go.
ill keep you informed to see if a rear block on the cpu socket helps with my temps at all...... gonna build one custom ... ( i know i keep saying that but i mean it, life just keeps getting in my way... )

tight=less loose = higher ( numbers )

Lower numbers is tighter...

@d1nky:

Alright, there are 2 aspects to RAM.
1: Speed. the Mhz they run at, pure and simple. Higher is better. Programs such as RAMDisks and VMs like more speed.

2: Timings. How long it takes for a request to go through. Lower is better. OSs and most games like lower timings.

There are 4 timings that matter most, and all are visible in CPU-Z on the memory page:
CAS# Latency (CL)
RAS# -> CAS# (tRCD)
RAS# Precharge (tRP)
Cycle Time (tRAS)

When you change one of the first 3, you change the 4th with it. The equation for this is:

(CL) + (tRDC) + (tRP) - 3 = (tRAS)
For example, 9-9-9-24, or 10-10-10-27, and so on.

There is also a 5th, bust much less important timing called Command Rate (CR). 1T is faster, but 2T is more stable.



How you OC ram depends on what you are trying to do.
_______________________________________

How to overclock for speed:

You raise the RAM speed little by little until they system becomes unstable. When it does, you have two options available to you.

The first option is to loosen the timings a bit. If you started at 1600 10-10-10-27, and now you're at 1800 10-10-10-27, but it is unstable, you would try 1800 11-10-10-28, then 11-11-10-29, and so on until it becomes stable again. Then you start the process all over again, but make sure to write down the "stable points" so you have places to start again if you lose track.

The second option should only be used if loosening the timings is no longer helping, or you have to loosen the timings by a large amount. This option is to raise the RAM voltage. The maximum voltage you should use for DDR3 RAM is 1.65v. Your kit is at 1.5v stock, so this should leave you some room if you need it. Only raise the RAM voltage in very small amounts each time, the goal is to keep the voltage as low as possible while making the the RAM stable.
_______________________________________

How to overclock for timings:

You lower the timings one by one, testing each time to make sure it's stable. As an example, your set would go from 10-10-10-27 to 9-10-10-26 to 9-9-10-25 and so on until it becomes unstable. Once again, you have two options available to you.

The first option is to lower the speed of the RAM. Do not go below 1333Mhz. Lower the speed little by little, checking for stability each time. Once again, when you find "stable points", make sure to write them down, for the same reason. When lowering speed isn't helping, or you are down to 1333Mhz, go to option two.

The second option, again, is to raise the voltage. Like when overclocking for speed, only add a little bit at a time, and check for stability each time. Again, do not go over 1.65v.
_______________________________________

Testing your overclock:

Memtest86+ is a popular RAM stress test program that you can boot off CD and use. It will stress your RAM, and will crash if it is unstable.

Personally, I think the best way to test any OC is to just run your system as normal for a while. If it crashes, or throws errors, it isn't stable.
_______________________________________

My advice to you would be to find how far your RAM will go in either direction, then chose which one you want to use based on how the OS and programs respond and feel when using them.

Another alternative is to find a middle ground. Maybe leave your RAM at 1600, and see how low you can get your timings without reducing speed.

Upon looking back:

tight=less loose = higher ( numbers )

vs

tight = less, loose = higher ( numbers )

Yes, tight is "less loose", but it's not higher. Not trying to be a grammar nazi, it's just a pretty big deal there.
