post #2521 of 8112
Anyone stress with AIDA64 Stability Test? Is it any good? One Thing I have noticed is that if I stress the CPU/Cache and Memory running my FX8150 @ 4.8Ghz(16x300), all is fine. Stress the FPU and it freezes. Could the FPU be the weakest link to overclocking?

Vcore @ 1.524
CPU/NB @ 1.4v/
Ram @ 1.65v

CPU/CORE @ 47oC/39oC

a beta bios fixed it for me too. Just wondering if it is a universal problem.

12 x 1.25 => 15
12 + 3(25% of 12(12/4 = 3)) = 15
K8/K10/K12 => 12 Stage Pipeline
K15 => 15 Stage Pipeline
Even then most applications for AMD don't use AVX or FMA4
You can tell 3dmark is using ICC because Pentium 4 EE = Athlon FX-55 = FX-8150
All 3 of them supports SSE3
FX-8150 should equal i7 3960X in this single core benchmark... or appear next to it by 33%(2000-2200 score for 3dmark 11) but it doesn't so FX-8150 isn't using AVX
Pentium 3/Core were both 10 Stage Pipelines I believe....Yet no one is complaining about Sandy Bridge's abysmally long 14 stage pipeline tongue.gif
10 -> 14 is bigger than 12 -> 15

sorry about quote thing but he right and wrong it's not SSE3 it's only SSE2 for what I've read.

I had about thirty minutes this morning to fool around with clocks on my FX-4100 and run a few quick tests.

At stock I noticed my memory latency really sucks, with maxmem reporting over 90 compared to about 50compared to my phenom II. Some tweaking and I brought it down to 70, which is still unbelievably bad. Maybe BD likes RAM speed over latency...who knows.

On that note, I noticed that CPU-NB multiplier has a cap of 13, although I brought it up to 2700mhz with 1.28volts. I didn't notice nearly as much memory performance increase as I did on the K10.5. Any thoughts on this?

I did get much better maxmem scores when CPU frequency was pushed. I'm sitting at about 4600mhz now, trying to find my stable voltage which looks like it will be in the 1.4v range. Seem typical? Stressed temps at this setting are still quite low, just low thirties celcius. Seem normal for good air cooled 4100 or are my temp sensors borked?

So...this HT link of 2600MHZ. You guys keeping it there? Any point in rasing or lowering it?

My first impression is mixed. I was very giddy as I was booting up over 4400MHZ at 1.25v, but saddened by the memory latency thing. I'm hoping that further tests show that high frequencies can overcome any shortfalls. I have my own database of my past bechmarks (AM2, AM2+, AM3) to which I'll be comparing. I'm mostly interested in seeing how well it does in gaming performance compared to my past AMD chips (Athlon 64, 64x2, 9550, 7750, 550, B50, 955, 1090T).

Definitely fun to play with something new. Even better that it was only $120 and came with free thermal paste and a $20 gift card.

Anyone tried core unlocker? I couldn't boot when I enabled mine at stock, though I will play with this further in verious settings.

FX is not unlockable at all.

Mid 1.4v range is about where many end up for 4.6ghz. Mine needs 1.48, but the only way to reliably get that voltage is to push it up to 1.5v (voltage will occasionally droop to 1.47 and cause glitches or crashes otherwise).

The latency issue is due to tradeoffs AMD made in the cache structure. It seems that they designed it with 4ghz as a minimum. I expect that the cache latencies will play a major part in the b3 stepping of the chip, along with a few other things.

@KarathKasun, what temperatures are you seeing when you stress 4.8GHZ? You tried clocking higher? 1866 RAM seem any better than 1600 RAM for BD?

What week was your Chip made? If you can remember...

Everything older than SSE2 is emulated from Microcode...and the execution units for those instructions are also emulated

Bulldozer really shines @ AVX-128/AVX-256/FMA4

I dont remember what week it was, I bought it 5 minutes after NewEgg dropped prices to $119 though.

Temps at 4.8ghz were horrible, 68c on the core temps, 75+ on the socket. Voltage needed for 4.8 was something like 1.64v. And this is with a relatively decent 120mm direct contact (heatpipes contacting CPU) HSF. The VRM's were hot enough it was kicking down to 1.4Ghz every 10-15 seconds in OCCT stress testing (no extra VRM cooling at the time). Ill have to try again when my Delta 120mm fan gets here, 250cfm of win!
