Hi! I've been trying to OC my 64 3500+ cpu on 2 occasions. I can get the pc to boot at 2.6ghz but thats about it. I've narrowed it down to my RAM. I got Kingston Hyper X PC3200 dual channel in my rig. I've maxed out the voltage on the cpu and ram but it still doesn't help. I've played with timings on the ram but it seemed to do nothing. Can someone explain to me the terms " Loose and Tight timings"? I've read the stickies and searched the web but I can't seem to grasp the idea of how the RAM timings work. Thanks in advance. :cry:

Sorry to tell you this, but it's the HyperX, it sucks. I had the same exact chips, and I could only get 2.4GHz out of mine at 11x217.

I then replaced my Kingston with OCZ, and now I'm at 2.6GHz 11x233.

good luck...

What are your current RAM timings? What voltages, FSB and multi are you using?

I can run it at cas2, ras to cas 3, ras2 cycle time 10 @ 2.7 volts. the cpu is @ 10 multiplier fsb gets up to 209 then dies.

An example of loose timings is 3-4-4-10 and tight timings 2-2-2-5. Tighter the timings, the better the performance. The numbers correspond to CAS-TRCD-TRP-TRAS in BIOS. You may get a few more Mhz if you loosen timings a bit but not much. Long story short, your RAM isnt very good for OCing, use a divider if you want to OC the CPU.

Yeah i figured the RAM itself was the problem. I was looking at getting this: http://www.ocztechnology.com/products/memory/ocz_el_ddr_pc_4200_platinum

Would this be a good substitute for what I have in my rig now?

;) now you're talkin'.....

Let us know the results.

btw, i would change your multi to 11x with these mem timings: 2.5,3,3,10
and give the mem voltage at least 2.8-2.9v.

well i just found this: http://www.ocztechnology.com/support/motherboard/100

I guess that RAM won't work. According to MSI the motherboard only excepts DDR400 and below. :cry:

I'm pretty sure that doesn't mean anything but double check it. I had a NF7-S and it was only rated up to DDR400 but I put pc3500 in there and it ran just fine. I've even put pc4000 in for a while and it worked too. I think they just put that in there because people might buy faster ram and expect it to run at that speed. It will work but only run at DDR400 unless you overclock it.
