AMD Phenom II X3 700 Series OC Club - Page 359

post #3581 of 6432
Hey guys here is my new overclock.

Look at what my RAM can do. At stock it is 800 MHz 5-5-5-16. I overclocked it to:

1074 MHz 4-5-5-15.

Also I overclocked my NB from 2500MHz to 2617MHz. +0.175 V on the CPU-NB is okay right?

- Clock Speed: 3624.5MHz
- Bus xMulti: 201.4MHz x 18
- RAM Speed 1074MHz 4-5-5-15
- Vcore 1.44V
- HT Link 2013.6 MHz
- NB Speed 2617.5 MHz
- Motherboard GA-MA790X-UD4P
- Chipset 790X
- CPU Cooling AC 64 freezer PRO PWM
- Number of Core's 3
- Cpuz Validation http://valid.canardpc.com/show_oc.php?id=606933

alrighty, i bought longer screws, now ive mounted the damn thing togehter, but wow.what a surprise..IT BSODed me.to..the point where i scratched my head so much...i ponder..wth is going on now? the board? the cpu? well notihng..ive realized that i might of lost the ability to OC..why? because it wont start up with any oc settings, thus; which made me concluded the theory that, for thoes of us that are running on hybrid, x4 mode..DO NOT TAKE OUT THE CPU OUT OF THE SOCKET..cus i did this for cleaning before reapplying thermal pastes, and the fix was..reset bios, then ofcourse reinstalls windows. ill see if i can still get the board/ cpu to still OC after win7 installation finishes. but yea, just wanted to share, or maybe someone else can test/ confirm this, if youre running on x4/ hybrid acc, take out the cpu from the socket, put it back in, and see if it you can boot into windows, if it doesnt, just clear cmos and reinstalls windows. someone pls test this, if you have a secondary rig, if this becomes proven, i think i'll just email gigabyte and see more fixes in this ACC bug. ill post up pics of the mountings once win7 installs.

**and so, it seems like, i can no longer control the cpu volts..it stays at default 1.3 period..wth happened to my board..sounds like RMA for me..

based from my experience, i need to scale 0.05v on the vcore for every 100mhz increase to be prime stable, say

3.6 = 1.325
3.7 = 1.375
3.8 = 1.425
3.9 = 1.475
4.0 = 1.525 (actually could not pass a run on this clock because of heat)

i use cinebench to test 100% cpu utilization to know what volts i needed to run them on such clock speeds, then if i pass i run prime95 to check cpu-nb and ram stability. if i get bsod, i adjust the nb volts or ram timings, not the vcore. but i usually use superpi to check nb and ram stability.

but in reality you can turn down your vcore to at least 0.025v to where you passed your cinebench run at, it's not gonna be prime stable but you're not gonna run upto 100% cpu utilization either, well that's just my opinion, take it for what its worth

weird problem, shouldn't be doing like that in my opinion. sounds like you need a bios flash

+0.175 (1.100 default) = 1.275v

sounds about right to me

Thing is Air cooling can be quite noisy when trying to keep temps down, i'm rock solid 5hr LinX stable at 3.6GHz but when i under volt my fans for night use, my overclock will crash after 15 mins of gaming. So quite water cooling would be nice.
i came from a coolermaster v8 to a swiftech h2o compact kit and i can say there's quite a difference of 5c, but if you can get hold of a triple rad, you might get much lower temps. i've been planning to get that xspc rx480 $109 at tilatech and ship it internationally. we don't have much watercooling gears here in singapore.

guys i would like to know why we dont add more NB frecuency because in the list , the mayority of you have the NB at 2000,???
Edited by Ghostcracker - 7/19/09 at 10:55pm
post #3589 of 6432
no, we oc the nb for better performance as well, the list doesn't show much because mostly new members that just got their 720s oc the core quickly and post their results, they haven't given it much time

you probably need to test it yourself because every cpu is different, some can reach 3.7ghz with 1.4v some only 3.3ghz...
I'm not heat problem, really. 1.5V does feel pretty high.
Do you think I will feel a performance change if I lower the multiplier to stock again and raise the front bus so I will be in 3.42ghz? I mean will be a lot higher and it might make a difference.
