XFX 650i Ultra VDimm Mod

[Supra]

As many of us know...the XFX 650i Ultra board has a very limiting 2.1V max on the VDimm which limits memory overclocking a lot.Here's a new mod that was put on the net very recently

EVGA 650i Ultra vdimm mod - XtremeSystems Forums



As this is quite easy.....can any of us here try it out & post the results

I have a Kingston Value RAM,Whats the max i can up the volts without frying it?I'm on stock cooling

 

[nj_gamer]

Actually its for the EVGA mobo...guess it will work on XFX too...

Both r same nvidia reference mobos....so the voltmod will work.....as of for Kingston value ram ....2.1V which is max on the mobo is more than enough. Volt mod will be required for hind end RAM with D9GMH chips esp

I did think about volt modding my 650i Ultra but it's a great board for memory, and I don't see a dying need to do it (yet). I'm able to run a single Transcend DDR2-667 stick at 800mhz 4-4-4-12-1T @ 1.9v... with these results, I don't think you'll have a problem running quality memory at their rated speeds. I've come to believe this board is over-volting memory, so 1.9v I set in BIOS may actually be 1.95v.

I saw while Clocking my E6600 on P5N-E SLi and Transcend Value 667 RAM, that 2.018 is the Ram voltage I have to maintain, otherwise, either system wont boot, or in load it will give hardware failiur Blue screen death !!!

2.0v required for what speeds though? Transcend DDR2-667 stock timings and volts are 5-5-5-15 and 1.8v.

@Rio
Did ya get a rounded IDE cable for the XFX mobo?

 

[RiO]

Yes, I did... I posted pics too in the Core 2 overclocks thread.

The standard Transcend Jetram, and all probably use the same chips.

Was the box sealed? Contact the dealer or XFX and tell them you didn't get the rounded IDE cable and ask for one.
