I'm having trouble getting my g skill pi's running stable at the rated speeds.

I have run memtest86 for 20 hours without any errors, but when I run the blend test in prime 95 i get errors within 1 min of testing :bang head. I'd realy appreaciate it if someone can show me what im doing wrong. Read below for settings.

Try setting the CPU at stock and just overclocking the ram (if at all possible), memtest is a good test of memory, so it seems to me like you have a CPU OC related issue, not ram.

as far as i know my cpu is running pretty close to stock 225fsb x13.5 multi = 3.037ghz

Try these voltages...

Code:
CPU/NB Voltage: 1.275V
HT Voltage: 1.26-1.28V
NB Voltage: 1.26V

Ok so I set all the voltages like you said I should. 1.26V on the HT seemed to help a tiny bit but i still got an error, after about 2 mins. I then increased the HT to 1.28V and ran prime 95 for about 7 mins before it came back with an error on core 3. What should I do next?
 
redduc thank you for the help so far :beer:.

I think Bob might have been somewhat correct. Running at stock speeds my cores seem to be running pretty damn hot. I didn't realy think it would be an issue since I was running stock speeds but, I saw my cores hitting 59c yesterday within 10 mins of prim95.

I ordered a new heatsink to replace my stock heatsink (thermalright ultra 120 true rev C.). I'll post my results as soon as I get my new heatsink installed.
 
Code:
CPU/NB Voltage: 1.30 - 1.40V
HT Voltage: 1.28V
NB Voltage: 1.28V
SB Voltage: 1.20V

Ok I got my heatsink installed now, so i'll be running prime95 tonight when I go to bed with everything at stock voltages and speeds.

I did try those new voltages that you posted and they didn't seem to help. Prime95 failed after about 5-10 mins. Besides messing with voltages are there any other settings that I might need to tweak?
 
argggggg prime95 failed after about 30 mins @1066mhz :bang head. Max core temps were at 47c, so I dont think there is a heat issue anymore and, I've never overclocked my cpu so I dont think it is damaged.

Just wanted to add that I was able to run prime95 for 24 hours with my memory at 5-5-5-15 @ 800mhz with everything else on stock. Please someone help.

I think I finaly got this memory stable. I increased the FSB to 300, set the multi to 10x, and lowered the memory ratio (1:2), and prime has been running all night without errors :burn:. I just have 2 last questions.

1. Is running this high of a fsb safe?
2. What speed should I be running my northbridge at? (Curently @ 1800mhz)
