Help a brother out

post #1 of 9
Thread Starter 
I'm having issues getting stable on my 965BE @ 3.959. First off, I have set the RAM timing myself and have a good cooler on it. I never hit more than 50 C (that I can recall) and can run small FFTs in Prime95 for 24 hours. The problem I have is within a few hours of large FFTs and blend tests I BSOD. I have the 124 error which from what I read could be solved by upping my voltage. I have my voltage set manually at 1.55v in my BIOS but both CPU-Z and HWMonitor show 1.524 as a max (it flucuates quite a bit as seen here http://imgur.com/PN6vzW6).

Anyone have any ideas on how I can get my voltage to stay put or get it to actually hit what I have it set at?

Also...the motherboard is an Asus M4A88TD-V EVO/USB3

With your base clock set to 220mhz, the RAM is actually running 1760MT/s, the HT link and NB are both OCed to 2200MHZ as well.

Set your base clock back to 200mhz, set HT-link and CPU-NB multipliers set to 10X. Set RAM multiplier to "6.66" (1333MT/s). Set the CPU multiplier to 20X and try for 4ghz first WITHOUT all of these other sources of potential instability. Then, when you have the CPU stability confirmed (or sorted out one way or another), THEN you can overclock NB and RAM speeds (with or without the use of the reference clock, depending on how high you want to go or what settings you want to have access to). If you adjust the reference clock, pull back on the HT link multiplier to keep it as close to 2000MHZ as possible.

When working on RAM overclocking, you can go up to ~1.7V on most DIMMs just fine but some don't offer any useful scaling beyond ~1.6V so experimentation is worthwhile. In my experience on that architecture, RAM performance was best in the 1200-1600MT/s range with tightest possible timings. Trying to achieve higher clocks wasn't beneficial.

When working on the CPU-NB, there is a lot of performance scaling on this in some workloads. SC2 for example, returns 50% of proportional performance scaling with CPU-NB speeds on the phenom II (3ghz NB speeds improve performance by 25% compared to 2ghz) . People commonly push ~1.30-1.40+V through the CPU-NB to try to get to 2600-3000+MHZ speeds on this.

Hopefully you have the C3 version of that chip. The C2 would be a total pig to OC.

I do have the C3 stepping. I'll try these tips out when I get home in 12 hours as I thought it could be the RAM causing the issue even though I pass SuperPi 32.

Well I finally got around to attempting just a 20x multi and I crashed almost immediately. I'm not quite sure what you meant by 'set HT-link and CPU-NB multipliers set to 10X' as my only options are numbers themselves. Unless you meant to set it at 2000 which I can try as I left them both on auto.

On a side note...at 19.5 with everything else on auto except a 1.55 vcore I made it about 4 hours in a blend test.

Just means that 4ghz is probably out of reach unless you want to go into the danger zone for voltage. 3.9GHZ is pretty darn good on phenom II wink.gif

Yes, 10X just means "2000mhz" for the CPU-NB/HT-link. Some motherboards show the frequency, some show the multiplier, some show both, some show the differences caused by BCLK changes, some don't. It's a fine mess!

Now that you'd established that 3.9GHZ is probably about the limit, I would suggest pulling back to ~3.8ghz, and working on the CPU-NB overclock. See if you can get it to run in the 2600-2800mhz range. That may improve performance in some games and applications by up to 20%.

I'll give this a shot and post the results. Thank you for the very clearly stated directions. You know your ****.

Alrighty...dropped the multi to 19 for 3.8 and ran both the HT-Link and CPU NB at 2600.

Here are the results...

Hey that looks pretty good!

Last thing on the list now is to work through the system memory timings and try to tighten them up as much as possible. Start with Command rate (tCMD), then CAS, as those have the greatest effect on performance, then tRDC, tRP, tRAS, tRC, tFAW, tRRD, tWTR, more or less in that order. Using a quick benchmark to monitor the effects of the changes may not be a bad idea, as sometimes you'll run into scenarios that *should* be better on paper, but wind up regressing performance for various reasons.

Top quick tips to find stable performance tuned settings without a million restarts and having to work through all timings individually:

Use memory speeds in the 1333-1600MT/s range for phenom II. Set DRAM to 1.65-1.70V. (some chips can handle more, but I'll leave that risk taking for you to decide on independently, most should have no problems with 1.7V)
Set command rate to 1. Check for stability.
Reduce CAS 1 step at a time until instability or boot failure. Revert to lowest stable CAS setting.
Set tRCD to CAS + 2
Set tRP to CAS + 1
Set tRAS to CAS X 3
Set tRC to CAS X 4
Set tFAW to CAS X 3
Set tRRD to CAS / 2 + 1
Set tWTR to CAS / 2 + 2

With most memory modules the above guideline will be "close" to as good as it's going to get performance wise, and should be stable. There will probably be some room to tweak some or all of those other timings down a little tighter but this would be the "starting point" that will perform well as is.

You are a boatload of information. Thank you! One question before I start messing with RAM stuff. I have 2 sets of different modules. Will this be a big problem? I'll link some screenies of the CPU-Z tab.

EDIT: What should I use to test the RAM?
