Hi guys this is my first post and I would like to share my recent experience (2 days ago) overclocking on a EP35. I bought this for $95 at Frys on the 4th.
I've been working around the EP35 for the past 5 days. I've been trying to achieve 4Ghz on my e8400 (oem from frys B&M) and I can't seem to go beyond 3.4 without errors. I manage to boot up to windows at 3.6 but everytime I run prime95 after booting, errors start to pop up. It actually took me longer to start the overclocking process because I have experienced that dreaded, nasty voltage problem that is plaguing this board, where no matter how high you try to push the voltage up, it's sticking to its normal voltage. The EP35 that I've bought had the F4 BIOS. I've googled all over and I stumbled upon the F5C beta over at the gigabyte tweaktown forums. Same place where I learned about the voltage problems. After fixing the voltage issues, I played around with the board.
First thing that I did was to try and run memtest on my Corsair PC6400 XMS2 2x2GB with DHX. I found out I can go as high as 1066 on my memory. One thing that I felt really bad was when I tried to crank up the frequency, I can't seem to get past 3.4 (@ stock voltage) without getting errors. I didn't have a p35 to compare this with but with the e8400 and the corsair, I thought this was a solid setup and I can reach 4 ghz which is my ultimate goal for upgrading. I did try to raise the voltage of the CPU, MCH and FSB and some of the memory. I did play around with the voltages, raising it one at a time trying to go beyond 3.4 without any prime95 error. I tried and tried and even applied the max 1.3625 volts and to no avail. These actions actually have created havoc on my processor. It made it worse. Now I can't seem to go back to 3.4ghz at a stable pace with normal voltage. I tried to go back to my old setup but it looks like when I slowly raised the voltage on the processor, it was a bad idea. I played around for one more day and I got tired. I returned the processor and the board yesterday.
I will probably buy the P35 and forget about the EP35. Im thinking about buying the P45-DS3R to save the data from my old gigabyte raid array and then buy the p35 for my gaming rig. I was wondering if the retail e8400 is better. I'm waiting for a deal on the P45s.
