need help overclocking.......

[drewk302]

i am trying to overclock, i havent tried since i replaced my abit an8 sli with my dfi nf4 ultra. What a diffrence! the bios is so diffrent. I dont even know where to begin. I ran prime to get the fsb for the cpu i stopped at 300, all i want to get is 3.0. I ran prime for 8 hours with no errors. Now i am trying to get the ram to run with it and i am lost heres the ram i have : OCZ Gold 2GB (2 x 1GB) 184-Pin DDR SDRAM DDR 500 (PC 4000) Dual Channel Kit Desktop Memory Model OCZ5002048ELGE-K. thanks in advance. I did some searches and had no luck.

it will boot but i get the bsod when trying to run a program. I got these from another forum i just copied them and tried them.

Have you tried the 166 divider? That should put your ram just above spec.

 

I found an ocdb (overclocking database) entry that has the same ram, and is a similar setup. You could give those settings a try.

i cant get to pass memtest no matter what i do now. i tried lowering the multi to no avail?????

[drewk302]

ok i got it to pass orthos but i had to drop the multi to 140. that puts the ram at 214mhz. i should be able to see 250mhz. what should i do. is there a diffrence from 214-250mhz? i am running prime now, and will let it run for 8hrs but, i just want the best speeds i can get. thanks!

Try adjusting these

Max Async Latency and Read Preamble Time

[drewk302]

thanks i will try that now!

[drewk302]

occt completed stable!!!!!! thanks. now i will rum prime. hopefully its prime stable. thanks again.

[drewk302]

Ok i ran prime, in prime it has 2 worker threads the 1st crashed at 7hrs 40min with 1 atal hardware error reported. the 2nd worker thread i stopped at almost 10hrs no warnings or errors. Do you have any other sugestions? Can you tell where the problem is comming from with it being the 1st worker thread?

[SpeedEuphoria]

normally if it fails that far in it needs more voltage or lower temps, you could try more chipset voltage if you haven't already. Also you could just leave it as most applications will never cause that much stress. But if your looking for a OCDB entry or want it really stable then try what i mentioned above, maybe add another case fan or move around or change airflow direction, clean up the wiring a little, ect..

 

 

There will always be one core that has issues before the other, its just a fact. Taking the IHS off is an option if you haven't already, it could get you there, but its very risky and Heatsink mounting can be tricky

Drew,

 

You are already at almost 1.60vcore, and I wouldn't go much higher than that for 24/7 operation - even water cooled. Download and install CoreTemp and rerun dual Prime95 with CoreTemp monitoring and logging your individual core temps. Report back with the temperature of the cores at time of failure.

 

Change these settings;

 

LDT/FSB Frequency Ratio - 3

LDT Voltage Control - 1.30v

Chip Set Voltage Control - 1.60v

 

Drop your vcore down to around 1.575 and see what happens, plus follow speeds advice about improving airflow inside your case.

feel the ram when it's off. does it feel warm, hot, etc?

 

if it feels much wamer than you, could be hot rams:angel:
