Phenom 9950 Overclocking

[roofsniper]

try running the ram at normal 800 mhz and see if you can get 5-5-5-15 since those are the stock timings. plus gotvoltage has posted that running unganged should allow you to get better memory timings. http://www.xtremesystems.org/forums/...&postcount=522 then run some benchies and see if your current memory speed or the better timings would help. the cpus normal voltage is 1.232 volts. trying messing around more with the multiplier if you want to get a better overclock. also you might have to give the cpu more volts if that is the highest you can get right now.

I switched to ungaged and tried to change timings to 5-5-5-15 and again, the system shows 'post error occured' however I've noticed that with ungaged mode, the cpu temp went down. Is it possible?

unganged splits the memory controller on the phenom which is nice because you have two memory controllers instead of one. it is better for multithreaded apps but ganged is better for single threaded. and as gotvoltage has pointed out unganged also lets you get better ram timings. he got a better score on super pi with unganged because he could get better timings even tho super pi is multithreaded. and because it splits the memory controllers it should take a little stress off the cpu. i don;t think it would change temps but i guess it could.

Hi there,

thanks for your reply.
The voltage is set to 'normal' which is 1.300 V and when I tried to set my ram to 5-5-5-15 the system wouldn't start. Bios was asking me to re-seat memory and go back to 'last good' configuration which I did.
I've changed the voltage to 1.500 V, multiplier to x14 and fsb to 218 which makes 3066MHz but obviously the temperature went dramatically up.

Thanks

Way too much voltage for only 460 mhz.
You should get the same results with the default voltage..

If you are thinking of upgrading to a better VGA than maybe you will have problems with the 550watt.Especially if you will OC the VGA too.

Hello RASTAVIPER, no VGA overclocking for this rig, just trying to hit high CPU clocks. What voltage were you using for your 3.7+ ghz validation?

Ive just run off a superPI 1M @ 3600mhz using 1.585v CPU-VID, and 1.550v CPU-NB VID



Now I want to push higher, but dont know how to increase the CPU-NB VID on this DFI 790FXB-M2RSH, got it set to 00 in bios, AOD gives no options to increasing this past 1.45v

Going to see how high I can get a validation



Also got a problem using AOD to increase the HTT speed, even when not overclocking if I increase the HTT by 1mhz it results in a hardlock. Anyone have any ideas why this is happening, as without HTT adjustments in windows am a little stuck at tweaking ..........

Aggghhhhhh need more NB-VID!!

Hi there,

what is the max temperature for 9950 black? According to the amd www it should be 61C but everest was showing 77C at one point.
Also how high do you think could I go with my processor and wth my cooling?
For some reasone when I try to change memory timings to 5-5-5-15 the system wont start showing me 'post error occured' message, then I have to reset the settings to be able to start system.

Ohh. one more thing, AMD OverDrive Utility doesn't recognize my processor. Perhaps it doesn't work with vista x64?

Thanks

Hmm the board gives you NB VID if you hit F5 (not 100% sure if it's not an other F key).
Beside that you can edit AOD's preference.xml in the aod program folder.
Change MaximumVCore Enable to 1. I expect it will allow you above 1.45V for the nb also.

Hmm, too low mem voltage, too high ACC maybe.

During some ait limit testings I found the 9950BE works without errors till ~85°C cpu temp (core temps are ~10°C lower here). Above 85°C the system started to freeze. I'd not go above 70°C worst case 24/7.
Can be your mem requires too high tRC for CAS 5, It's a common issue with normal dimm's.

Thanks for your input, its F9 for this mobo and 00 is the highest (as in most voltage) setting that can be inputed giving 1.550v. Wasnt familiar with the ini editing in AOD as this will hopefully be what I am looking for

Will give that a try, the next time I have an attempt at OC'ing.

ACC is on auto, so its not that, also mem voltage is more than enough for what I am doing. Have flashed back to an older bios and will have another play the next time I get a chance.

Will also be looking at 'freezing' the water in the reservoir at some point. Simply put going to get a icebag, fill it with solid ammonia blocks and then dump the reservoir into it



Only worry is condensation, but there is good airflow in the case so hopefully that wont be a problem.

Looking at the clocks I am hitting at current temps, if I can decrease water temp to near 0C then providing I can feed the NB-VID with more volts, 3.8+ ghz SuperPI 1M results should be achievable.

Then as soon as Phenom II is readily available the platform will be ready for testing a 940. Looking forward to that, been a long time for me to test a newly released processor.........

set the ht and nb in the bios to 200x12, set the cpu to the higest oc you can get it to boot into windows (eg;200x17.5....3.5ghz) then start ocing through aod in windows for that last few mhz...use version 2.1.4 of AOD. I have no problem moving the Ht.ref clock in aod like this.

[W.I.T.C.H.]

I want those results Nice Guys,

By toasting I mean a short on the 12V (4 or 8 pin connector) near Mosfets
I have RMA'd it for the 2nd time, waiting for 3rd mobo to come. (Hopefully this year)

I was at 1,45v Vcore air cooled my bracket for h2o is still under construction.
NB about 1,5v
vdimm 2,5 (Liquid cooled)

That was the end of it.
Nothing broke but the mobo. (ALL other components tested).

Maybe you guys can help?

Thanks

See if you can make toast with another PSU Two mobos with 4/8pin problem something other than Mobo is cooking.. 1 bad // or buggy PSU can Over volt a mobo easy.


Ive pumped the ASUS with enuff Volts to make just about anyone feel uncomfortable and trust me the PWM's will fail before that 4/8pin.

You could even have a piece of hardware shorting and causing Mobo failure once it gets to a certain limit. Pull any extras out of the mobo( Use one PCi_e Video card instead of three and retest.)..Your PSU may be giving dirty supply once its stressed to its limit,, then wham instant "How too Smoke Cookin on yer WeberMobo southern style"

LOL, well I was thinking wild turkey,

Anyways I ordered that famous Asus Board,
I haven't bought a PSU in over 2 years maybe that's why!

What make you recomend?

After bios downgrade, upgrade then AOD uninstall, re-install I can use the HTT in AOD to change clockspeeds. However the changes it applies are not updated in AOD



Also changing MaximumVCore Enable to 1, simply lets me set NB-VID to the max value in bios, i.e. 1.550v. I need more!!!!

Well my cpu doesn't like especially high voltages, so reaching 3.7G wanted only 1,55 vcore in BIOS.
Also I put NB at 1,3375.All others in AUTO for me.

Almost any good 550+ PSU should do the trick if you don't have a power hungary GPU (you'll probably need a 600+ for yours). I'm a SETI cruncher so my vid cards are very low-powered.

Fortron is a good, mid-range PSU and prices go up from there. Here's a good place to see who makes what:

This last week I fried a MOSFET on a Biostar 790GX. Transferred everything over to an M3A78-T and it's running fine - OC testing 3.2 GHz as I type. The only thing bad with the first rig was the board. In the future I'm staying away from Biostar ...

if you check cpuz its actually 1.6v , its what i used to hit 3.6ghz myself

You are luck my maxvalue in bios is 1.45v but when i did MaximumVCore Enable to 1 it went to 1.55v(cpuz 1.6v). but now i have lost high v in aod and they wont come back....so im stuck at 1.45v

Hey Titan7171 whats the MaximumVCore Enable to 1 setting you mentioned.Even I want to try that.

[Titan7171]

you go into C/program files/AMD/Overdrive/preferences

near the bottom xml document change from 0 to 1 will give higher v in aod.....it doesnt work for me anymore though.

First off, you cant set the vid past 1.55. For those boards that can go past 1.55, its not just vid, there's another hidden voltage bump. For example my M3A79 has a vcore setting in the bios that goes upto 1.7v. 1.55vcore = 1.55vid, 1.65vcore = 1.55vid + 0.1v boost, 1.7vcore = 1.5vid + 0.2v boost, with AOD i can push it to 1.75, which cpuz reads closer to 1.8, and with a load i've seen cpuz report 1.884vcore, but i havent found anything to let me set it above 1.9vcore.

The problem with setting htref clock from AOD is if you have any other apps running that poll the board (cpuz and friends), then it may cause a deadlock. Im not really sure if its something AOD can workaround, but we may see some improvements with this with AOD 2.1.5 which will be released with the Denebs.

As for losing the max vcore, there is a bug(again being fixed in AOD 2.1.5) that if your system crashes while AOD is making changes, it resets everything to default. You'll know its reset if you open AOD and its in kiddie overclock mode. Close AOD, edit the pref.xml file, and open it again and you'll have your vcore back.

Im curios, what kind of temps are you guys down to to get 3.6? I got my water setup the other day and ran some benchies. Load temps on water/cpu were around 11/19c at 3.55, got me a nice gold cup for my 9850 on wprime32, but i lock up on any attempt for 3.6

I have done a clean install of vista 32 and setting the pref.xml file to 1 does nohing. I have tried many times to reinstall aod and it will not go above 1.45. With a clean install I didnt oc so there was no crash to reset the pref.xml. In fact when I installed it the first time the file was already set to 1 without me touching it. So i still only get 1.45v. I may just get another mobo

Reset your bios for a sustained period of time, i.e a couple of hours, if that dont work, reflash it. Do all this with AOD uninstalled from the system..............

How did you manage to get such low wprime?
It's excellent score!!
My best was 10.750 at 3.5G with 4-4-4.
The only major difference is in memory frequency.
You are at 610 and I am at 474.
Is this, so much difference??
