aaaand heres the problem with my rig at its current settings.. :S somethings wrong?

aaaand heres the problem with my rig at its current settings.. :S somethings wrong?

I'll look again in the morning, but right now the bottleneck seems to be a horribly cluttered desktop!

Sorry it's about 3am and I really need sleep.

(i've attatched what my desktop looks like for comparison purposes so you may optimize more efficiently)

heres some pics of my rig..while running i touched the cpu heatsink - if it was idling at 55c the sink should be rather hot shouldnt it? ...well its just warm to the touch but certainly not hot. also i included some screens of my bios. Can anyone shed some light on my situation?..

 

[Flyordie]

Well, I have to leave the OC club for a bit... the 790GX DFI board I bought off Shadow died tonight. Went to restart after an 2hr long Crysis Warhead run and wouldn't POST.
Looked at the LCD thingy and said "88".
Hope to be back shortly. ;-)

Hello everyone, i would say im quite experienced with computers over the past decades, but still a newbie when it comes to overclocking and especially troubleshooting OC issue.

I build a AMD 940 rig for my brother with the gigabyte 790gx mobo ( F3 bios) non UD version.
Other specs are GSKILL 4gb ddr2 1066 ram ( also running at that speed )
Corsair 650watt TX
HIS 4870 1gb ICEQ turbo
Zalman cpu cooling

The system is basicly rock stable, if it wasnt for the occasional crash to desktop in COD4 which happens like once a week. At first i figured its simply windows as we know it, unpredictable.

But then i read on the AMD forums about a guy writing down his experiences OCing his phenom to 3.8ghz, and he described how he knew the CPU didnt get enough voltage when the system seemed unresponsive and icons disappear etc. Thats when it hit me that hows my bros windows reacts once crashing to desktop, windows doesnt seem to work properly anymore till a full restart occurs.

Now to the facts of the OC, basicly i set the multiplier to 17 ( 3.4ghz) and thats it. I read tens of reviews where people hit 3.4ghz on stock voltage. And it works just fine on my bros rig till some heavy gaming occurs, and even that its really really rare.

I added 0.100 voltage to the Vcore, northbridge, and southbridge. I figure i have still alot of headroom voltage wise cause its a quality board and PSU. what i am worried about is heat though, standard Vcore the cpu got 44C hot, with only 0.100volt increase it shoots up to 50C.

Also i wondered what kind of other bios tweaks you guys apply? Besides the above steps, i set the RAM voltage to the appropriate 2.1v and set all the latencies as shown in the SPD of the ram.

Looking forward to any input

That needing system restart to start working properly I would say that is corrupted RAM mem and with restarting mem is rewritten. That could ocure because of faulty ram incorrect timings lower than needed voltage also unstable CPU overclock could corrupt what is written to the RAM memory.
You can try this with finding some software that could empty RAM memory. I`m not remembering what software was for optimizing in witch there was option for emptying RAM mem.
Example I`m running my PC at unstable overclock and I try to install some software and I start the exe and it says to me that is corrupted I try to start the install couple more times and the same error because the software is written in the ram mem corrupted so I use this software to empty RAM and I start the install and it installed correctly.

 

[Flyordie]

The board is ALIIIVEEEE! me thinks... POSTed to 7F (which was expected)... sooooooo yay.

I have a Problem i have a 940 but 1 of the cores wont show up any more on AOD i did a Bios Update on the Foxconn A79A-S and i dont know if that is the problem anyone have any ideas what it could be?

 

[OzzmanFloyd120]

Does it show anywhere else? CPU-Z for example?
Something else that makes me curious is whether or not it's stable when you stress all four cores, because worst case scenario is that it may have a faulty core.

Its back to normal on CPU-Z and AOD but the Welcome Center Screen Shows it at 1.64mhz

Going to try to overclock it again maybe it will work brb

 

[Assassin48]

Never mind it still shows up with the wrong CPU mhz i dont know what happend

edit Going to update it with the last one maybe it will fix it

 

[Assassin48]

Well it looks like i fixed the problem all i did was just update it again and now it works

I saw that the new CCC 9.3 just finished dl and will install and post some scores!

Yea it works for AMD chipsets. Unfortunately it wont allow my chip to go past 1.55 though. I got to 3.9 but it wasnt stable.

push your FSB to 215 and then move the multiplier, if you set the voltage to 1.55 and then raise the htt the voltage goes up incrementally. with a 1.55 setting and htt of 215 my true vcore came out to 1.6v, some kind of auto voltage bump when the htt is pushed.

at least it does that on my M3N-HT NForce 780a. i dont know if its a feature of amds doing or nvidias?

BTW i bounced off of 4100mhz but couldnt get the validation

 

[Flyordie]

1.35V but reads a bit high on CPU-Z.

 

[Master}{]

on mine if the htt is 200 then a bios setting of 1.55v produces 1.56 vcore,

BUT if i move the htt to 215 or anything over 210 it bumps up by .5 V automatically according to hardware monitor and cpuz

so if i do 215 htt and set voltage to 1.55, i end up with 1.60v even, if i bump the htt further it does it again!

hello new to forms thought i would share my amd rig with you all

what aircooling would you guys recommend for the 940? im thinking either the TRUE or a Cooler Master V8...However ripping out the motherboard will be a mission. How does Xigmatek stack up against these two?

 

[ShadowFold]

Xigmatek S1284EE is the best cooler I've used on my AMD systems.

 

[Enmity]

thats the archilles isn't it?

[ShadowFold]

Yea, the Achilles is just a better looking version, essentially the same thing tho.

 

[Enmity]

Sweet, i might grab one of those then. You dont need to remove the motherboard with those either right?....two ticks for me Hey thanks Shadow. I'll order one of those badboys today...ive been told in another thread that my current AC Freezer 64 mounting surface is too small for the phenom 940...which might explain my hideous temps.

 

[ShadowFold]

No motherboard removal at all. It just clips on like every other cooler

 

[Darknova]

Well I ordered some new parts this morning. My PC won't look the same after tomorrow

 

[Enmity]

except for the TRUE and the cooler master V8..as far as i know you have to remove the motherboard for those two beasts

 

[ShadowFold]

Looks like I won't go DDR3 yet, but I will buy a 720
