So what exactly am I supposed to do? When I put the ram frequency back to normal, it made 2 very long beeps, and then booted up, and set ALL my bios settings back to default, and it wouldn't boot any further.

So again, do I give it looser timings, or what?

Isnt the HTT bus a multiple of the RAM, not a divider (200Mhz x 5=1Ghz HTT Bus) and the CPU speed is also a multi of the RAM speed (200 x 10 (cpu multi) = 2Ghz). Take my new CPU for example, if I overclock the RAM to 250Mhz I get 250Mhz x 5 = 1250Mhz HTT Bus 250Mhz x 10(opteron 146 multi) = 2.5Ghz. If mossimoboy overclocked his CPU to 2640Mhz his RAM should be running at 240Mhz to be properly sync'd up with the bus since his CPU multi is locked at 11. Correct me if i'm wrong.

Thats a good point actually.

My HTT is 240MHz but the ram (according to CPU-Z) is 188MHz.
But yes, I think the HTT is a multiple of something (not a divider) because when I check the HTT multiplier, all the settings are times (x) a number.

240 HTT x 11(cpu multiplyer) = 2640
236 x 11 = 2600
Setting ram at 333mhz(or sometimes 166) is a 5:4 divider (cpu:ram) A64 can't divide correctly.
CPU : RAM
240 : 192 but is 188
236 : 189 but is 185 - the "real" divder even changes with the cpu multiplyer.

The slightly slower RAM may be a problem, but you have another bottle neck(video card.)

Try 260x10 5:4 if your memory can hang at 217mhz. Alot of PC3200 can.
Try that little program attached here to see real A64 math. :haha:

no, HTT is not a multiple of the RAM. you are confusing different settings

the HTT multiplier sets the HTT bus speed. the RAM divider sets the RAM speed

mirob explained it well in the above post

Yes, I did have v-sync enabled, but when I turned it off I got only 1-3 more fps.

The program didnt do anything, it just turned my DRAM frequency into a decimal.

But also don't forget, the

What I had ment is it increases the bandwith on the graphic card.

By OCing your CPU.

On the PCI-E Bus

I just set it back to normal. There was basically no performace increase, and all I had was a hot piece of metal in my computer. Besides, the vnf4 ultra isn't a good board for overclocking.
