Yes, on AMD. Also on Intel.

Used numerous settings in the past. Everything from small ffts, to using every available bit of my memory and everything in between.

X.264


Prime just isn't that great for stress testing anymore. LinX works much better. Pushes the temps higher, as well as just stressing the cpu and ram in general.

thats my experience as well. linpack x64 is the only thing that comes close to actual stability testing

Wile are you talking about the bench?

As for LinX every time I've ran both I've always been able to pass LinX only to have P95 fail if left running longer. Although the only time I've used LinX and P95 was for testing CPU-NB stability. I don't know how you both are getting different results. It has been very consistent for me.

For a C3 stepping quad, is 1.52v+ normal for 4Ghz?

Sounds like mine that I had. Needed 1.525v for a straight multiplier jump. I needed 1.3v for 2600 CPU-NB fwiw.

What's your batch code? Mine was CACAC AC 1004CPMW

What bench? I don't follow.

You are running Linpack for half the time. Leave it run. And if you set it up properly and run it in x64 mode, it stresses the memory and the cpu harder than Prime95, without exception.

I use OCCT for my linpack testing, as it lets me run it in infinite and is just easier to deal with.

^ what he said.

a 32 bit stress test is useless on an x64 OS, since it doesnt test all of the CPU. those untested parts could be unstable, and cause the OS to crash even when you pass the 32 bit tests fine.

IIRC, 1007BPMW. What's bad about it is that the board I am currently running has no cpu-nb voltage adjustments, so I have to leave NB between 2-2.2, as it's VID is 1.175.

Here's where I am currently at with my 24.7 clocks

each board that supports am3, supports cpu-nb... me for example also has no option for that in the bios, so i just use K10Stat (provides chageable cpu-nb vid) and my mobo manufacturers htt clocking tool to clock the proc to its final speed.
basic settings are made in the bios though, preferably those that cant be adjusted from windows like certain dividers and volts

Well either way, I am still working on getting the most out of this chip. Working on 3.7Ghz as an x4 right now. I am aware of k10stat and what it does. The problem is what if I want to push like 2800NB, it posts but can't load windows. Never said it doesn't have cpu-nb multi adjustments. Anyways, I hate to complain, right now that's what i am doing.

I found OCCT to be very sensitive to other software like core temp. Even if core temp isn't running the fact its installed will mess with OCCT. I have NO IDEA why but it does. I've done a few experiments with it. I once did a clean install with no change to the bios and OCCT ran awesome. However when I installed OCCT or G15 software I went about 50 minutes and she would bomb. I can't explain it.

disable all temp/voltage monitoring in OCCT, and the conflicts go away.

you cant change the CPU-NB multi normally in K10stat, but the volts

im doing it exactly like this:
1. clock the proc in the bios, until its stable using multis, the htt stays at 200
(volts can be changed later if needed)

2. use nb multi 12, to get 2400 mhz NB, because with even 2600nb, windows wont boot,even for me
(remember to use the right memory divider/timings/volts, so you will end up with the right memory clocks later, and not unstable or too high ones)

when windows booted, use k10stat to change the CPU-NB to the voltage of your wished test value... also, Multi adjustments work here without crashing (in opposite to AOD )
raise the FSB to the desired Value.
this needs a bit attention, because you roughly have to calculate what clocks you will get, before you set them in Windows.

if that still crashes, your proc is probably at the end

disable all temp/voltage monitoring in OCCT, and the conflicts go away.

Exactly those 2 things that make OCCT attractive in comparance to LinX

i have a a79a-s foxconn mother bored and a amd am2+ 940 chip and i dont think i can get it any higher then 3.6ghz i was wondering if anyone knows a way to get it more stable and iv tryed putting 1.6 volts into it and it wont stay at 3.7ghz but its fine @ 1.4v at 3.6ghz would it be somthing else holding my cpu back? or whats the right ht volts needed for better oc?

Sounds like my wife's 720 Black. 3.45Ghz is golden @ 1.4v. Anything past that core clock regardless of voltage, instant lockup and wont even post past it either.

Got the Mushkin RedLines DDR3 1600MHz CL6 in.... 4GB flavor. Guess no need for 16GB, yet i'm still tempted for 8GB DDR3 1600MHz RAM. Latency-wise should be nice addition to 955BE in case & i'll play with clocks, NB:RAM ratios & stuff like that. Or is it ? See you on the other side of Cha..... erm, 4GHz Club. lol

 

[catnipkiller]

can i boost my ht volts for a better oc ? or is 3.6 my cores max oc and if so what would be safe ht volts?

Not at those speeds. 1.35v is fine, you don't need that much except when running extreme speeds(5ghz++), and more often than not, the stock 1.2v is perfect.

HT is only used for chipset/cpu/sb communications, so unless you are upping HTT(FSB) over about 265 or so, there's no need for any increases.

Tech ARP x264 Benchmark

If you guys are using the x86 version of Prime 95 that would be your problem. x64 version, bottom link

I've use both x64 versions P95 and LinX. P95 always proves out over LinX, or any linpack for that matter, on AMD. If I'm P95 stable on my AMD overclock I never, never have any bsod. Games, benches, encoding, riping, etc never once has proven unstable after P95 24 hour pass.

I looked in the manual I have for that board. I can't believe there is only nb, sb, and vdimm adjustments. What a rip! I hope you got it for free or something. Only reason I got mine was because it came with the Athlon X3 that unlocks with L3. Fwiw that chip is the same letter code (BPMW) just an earlier date and it does a little better per voltage wise on the CPU-NB than my 555 did and the Athlon is a C2. I had a 550BE that unlocks and it is a pure dud compared to the Athlon with the CPU-NB. The Athlon really acts a lot like a C3 on the CPU-NB part.

 

[mastrdrver]

Hmmm, how is it possible to run dual channel with AMD with 3 dimms?

 

[JrRacinFan]

Bank interleaving. I myself have done it in the past.

[mastrdrver]

Did it give you a lot of trouble when tweaking timings?

It could be the ram but seems like its a nightmare to try and tweak.

Not at all. Was the same as if I was clockin' 2 sticks.

 

[YautjaLord]

still not there ?

With 3.5GHz clock ? lol'd No, still not. BTW : of 2 - HAF932 or HAF-X ? Which should i go for performance-to-price-wise ? 932 is obviously ~70$ cheaper. Take care, dude & thanx in advance.

i would get the cheaper one, but i also admit im one of the guys that doesnt pay much for cases

 

[YautjaLord]

HAF932 is also loud for quiet hood with it's dBa, CFMs & RPMs - 3 f***ing 230mm fans 2000RPM each, imagine how loud it will be with 3.7 - 3.9GHz clocks. I'm affraid to say 4.0 since the highest was 3.9GHz & it was totally unstable. BTW : i am just like you too with cases - don't need a fortune to buy one as long as it does it's cooling jobs nicely/as it should. Thanx for advice.

 

[catnipkiller]

what else should i change to get a better oc or is this chip not able to get past 3.6ghz? my temps are fine idels 20-25deg gaming 40-50 but no matter what iv tryed it just wont get past 3.6ghz i dont know if its the chip or i'm missing something.

the chip is probably at its end, if you dont want to buy expensive watercooling gear/ high end air coolers. but 3.6 ghz is already ok, thats quite fast.

Have you tweaked the NB and Ram Subtimings yet?
