Phenom 9500 w/ MSI K9A2 Platinum

[KTE]

We're past the 12hr mark in stability perfectly now and I don't see a reason to continue at this setting. Here's some good knowledge for you though:
higher CPU temps>higher current leakage>higher CPU power draw.

You saw 217W AC max draw before at the same MHz but low ambient/CPU temps. Now I've left everything running and as soon as I increased the ambient temperature and dropped the HSF speed to lowest, the same load is now pulling 13W AC higher at the same PFC consistent. Move the temps down and you get 215-7W AC back again, even though it should increase since the fan pulls 3W AC going from lowest to highest speed.



2525MHz / 4cores 1.320V idle/1.30V load
1818MHz IMC/HT
539MHz 5-5-5-15-29-2T RAM
12hr stable, 50C max CPU temp reached.
Idle 110W AC
Full load:
230W AC high ambient-bad cooling.
217W AC low ambient-good cooling.

NB VID can go lower to 1.2VID stable at those NB MHz (2.2GHz/2.5GHz will need the above VID though) and thus total power consumption will also decrease a little.

I've found what causes my system lockups! The cores jump in MHz wildly at some second now and then. I had a lockup just now and I managed to catch it while it happened at 2.3GHz. Core 2 and the NB jumped to 2.68GHz randomly and that caused the system to lockup. Don't really know how to work around this or where the source of the problem is here.

For reference to MSI K9A2 Platinum users, CPU and NB VID 25=1.237V, 24=1.250V .... 15=1.337V and so on. Just FYI.

Well this is G2 silicon and from my experience so far (just a few hours of playing) it is much improved over G1.

Can't really comment based on memory since my own experience with G1 was long ago. Through observations, I would say something similar.

I wonder if it's due to the board or the the cpu. Is it the same for other users with the 9500?
2,35GHz is max. stable jpierce55 and I can get at stock.

Quite frankly, it looks like the CPU to me. The only thing it can still be is the RD790 clock generator which is what causes most of the oc errors around with people. It is hard to debug though, I'm trying to find out it's MSR to read the registers but haven't got anywhere since there is minimal official documentation on the RD790.

It's a nice playground in terms of settings and it does not cost more than the 9500.

Well the firm I picked up the 9600 BE from purchased both this and the 9500 at the same price but that's not true for retail buyers who feel it in their pocket first and foremost. US has it far cheaper compared to Phenom 9500/9600 and Intel C2Q than UK and much of EU does. Many [r]etailers are price gouging.

Not sure about performance in medical image manipulations as those are very memory and floating point heavy. Do you know how the platforms do in ct/mrt segmentation?
I plan to write a benchmark for those special tasks.

I haven't, sorry. A benchmark for that field would be pretty good to use, I hope it's Windows based though and not Unix.

I'm concerned about the board cooling with those horizontal mounted fan's. CNP9700 seems to do a better job here.
Do you think the extra cooling power provided by those 120's is needed for AMD cpu's.

Some of the AM2+ boards, in fact many of them, require a lot of MOSFET/inductor cooling and for those the 9700 works pretty good (since it can cool the RAM and CPU supply circuitry at the same time). The only reason for wanting better cooling would be a) try low temp oc b) lower noise c) better cooling price/performance really. K10 oc doesn't seem temperature limited at all, so whether you try the stock fan or a 250W TDP CoolIT freezone Elite, it doesn't seem to enhance the oc in any way from my experience and observations.

I choose a Gigabyte P35-DS3 board for my first intel rig, did not look bad but i missed basic memory timing settings. After I had it benched it suddenly did no longer boot with 1066 settings. Time was to short to make myself a good picture of it.

I actually like the Gigabyte P35 series a lot. Had a lot of good experience with them.

what's the difference between core voltage and core VID?

First is VCore and the latter is Voltage ID needed for the processor to set Performance profile states. It's a little too lengthy to explain accurately but in short, you have higher amps fed to the core with higher VID and higher VCore options available as you increase the VID (I've tried up to 1.74V).
