Phenom 9500 w/ MSI K9A2 Platinum

[KTE]

Just messed about with it, found some time. As you know I like to keep a track record of every time I mess about with it, I write notes in a TXT file to compare later.

WISE: in corporations these are a set of applications referring to Word processing, Internet, Spreadsheet and Email but cover all the majority of regular system usages.

Issues
*One of the biggest issues with Phenom 65nm B2 and Intel 45nm C0 is degradation, how, what, after how long and how to avoid or contain it.
*The second is low volts bench/screens but very high volts for real stability.
*The third is to avoid WISE stability problems.
*The fourth is how to have a perfectly stable system for our needs, in all tasks we will do not just FPU stability.
*The fifth is x64 stability and oc.
*The sixth is stability with 2x2GB and 4x2GB.
*The seventh is C1 errors at boot.
*The last being, does it respond to voltage after 1.39v? (unlike B2)

Load Stability Test
14x 200 2.8G is perfectly fine stock volts (1.296/1.288v idle - 1.276v load)
14.5x 200 2.9G is perfectly fine only for benches stock volts
15x 200 3G fails load stability stock volts outright

Idle+Load 24/7 Stability
2.8G was not stable - it froze after 16 hours during WISE. I jumped MHz.
2.9G was no go at 1.4v real, fails WISE stability after 8 hours although can bench easily.
1.4v 2.9G did not even boot with CnQ turned on. Disabled it then.
I jumped to 3G, that's my ultimate aim to see if B3 can get 3G stable and what limits it. Glad to say, 3G is within realms quite easily, mine is running smooth at 200 x 15 3000, benched it, primed it only 35 mins and am mainly running the WISE test now [256mins into it - 2/3 days is the test range for it].
BUT there's a caveat =>
After 2.8G you suddenly have to jump up volts very high to get any stability. It might seem no go to those who get whimpy after 1.4v AMD rates the CPU max 1.55v within range.

3.00G Stability
I tried every boot voltage, even 1.3v booted 3G but was not stable. I then just jumped to 1.558v BIOS, which gave me 1.592v Windows and 1.584v real. I then worked my way down. Lower limit was found, 1.540v idle will not be stable, will bench easy but fail WISE stability.

I have managed a stable setting. ATM it requires 1.552v idle and 1.528v load for perfect [so far] stability. This looks too far for many though. I have mentioned already, this is a hot and power hog chip esp. with volts. Here's an example:-

3G 1.6v idle was 136W DC just the CPU.
3G 1.564v load was 267W DC just the CPU.
On load, 84C at max fanspeed is easily reached! [cooler is not clamped down and without TIM, bear in mind]

3G 1.552v idle is 97W DC for CPU, which is what I'm at now. I have tried enabling CnQ and am successfully running it right now at 400MHz 0.7v with 3000MHz 1.552v being the load setting. CnQ gives me 12W DC idle CPU power.

Basically, this is an Opty 165 all over again. You will get 1.45-1.58v 3G and more fully stable but you will need a good cooler. ATM I am severely limited by cooling, for water, this chip should get 2.9-3.2G stable IMHO. I have booted 3300 max at 1.592v but it is too much for my cooling [yet] and it freezes on saving CVF file or IMG file from CPUZ. Installed the new AOD, it crashes my system pretty quickly which is worse than the previous one.

Here's what I'm testing ATM [setting right now]:-




Some [totally unoptimized] 3G benches FYI:-

Everest MEM/Cache


2k6


wPrime 32M


PiFast (Single threaded)


Fritz


NuclearusMC


Cinebench 10 2800, 2900 and 3000


SuperPi depends highly on MEM and with this, yet, I can't oc MEM/NB, so it'll have to wait. I'm expecting around 24.6s 1M at 3000MHz, its very possible to get 26s flat though.

Sandra MEM/Cache linear latencies I've checked out only at 2800.


The 1ns is L1 cache, the 4ns is L2 cache, the 8ns is L3 cache and after it is DRAM access.

Proper benches, i.e. tweaked will be later. Have to work this thing out first.

KTE: is it good result to get 1708 kt/s in winrar bench multithreading on cpu stock and mems on 1:2.66 divider cpu : phenom 9500 i was kinda stunned
mem timings 5-5-5-15-30-2t @ 2.1v bios version 1.40

On a 9500? Not sure, it isn't for 9600 though. 9600s stock 5-5-5-18 1066 can do 1872KB/s without optimizations with a decent BIOS (For MSI 113 will do that). Many BIOS kill MEM performance though.

Also ordered 9850 BE... i really hope... that iw will be good one if not ... have to buy second one.

Depends how you go about it and what you expect. I wouldn't base any hopes on what Tony showed, that is for water and above only.

yea sry opinion on the 9750 and have you do any idle testing to see if these are unstable at idle like the b2s where?

I've answered that above now and about 9750, no idea. I've not seen it myself first hand nor tried it and until I get to try 2 or more, I could never say. It may be just like 9600 B2 was, many good and many not so good.

So that means you want me to put it in the crosshair so I can get a prelim for how well it overclocks and such? I can do that as long as there is a bios to support the B3's. Too bad that system only has a 7300LE in it...

Don't have to but trying air and then vapo would be good enough for all

Sounds like you some DFI love Tye

If I go DFI, it has poor MEM oc/stability and I value that quite a lot
I'm running 2x1GiB 1066 5-5-5-15-11 75ns tRFC @ 2.05v with MSI stable

Also what would be a safe "guess" for stable expected OC from New B3?

2.7 to 2.8G stock HSF, 2.8G to 3G 3rd party air, 2.8 to 3.2G water is my estimate on 32bit systems.

Stop teasing us... show us that 3.5+Ghz clock

Hehe, kinda like no way on this cooling. I can POST and be in BIOS at 3500 though which is far better than B2

Hey Tye is the B3 Revision still get the Vista TLB Patch enabled?

Vista SP1 kills B2 MEM perf but nope, patch is applied based on CPU stepping code.

@KTE Could you please test and see if there are any stability issues in x64 vista and if can clock as high in it as 32 bit version.

Let me try and ascertain how stable 3G is in XP/Ubuntu 32b and then I'll move over to 64b systems to check the same settings
