Hello folks, I'm getting angry with my Mushkin Redline XP2-8000 (these ones (http://www.xtremesystems.org/forums/showthread.php?t=174940)).
They will flawlessy OC to about 1066 MHz 5-5-5-12, but I'm not able to get them stable at 1080. 1080 MHz is just the result of a nice 450*8 on my Q6600, with a 333/800 strap; any other strap would bring them under 1000, scoring awful in the Everest bandwidth tests.
400*9 with the 400/1066 strap scores similarly awful... It seems like there's some FSB need, in addition to RAM speed, to achieve some decent over-9000MB/s read speed and some over-8000 write and copy.
450*8 would relax my CPU voltage (which I'd love, and 3600MHz would be just fine) and allow, with the 333/800 strap, some pretty decent bandwidth results. A good mix. But my Mushkins don't handle that :down:
I tried a lot of playing with about all memset timings, plus relaxing the extra options in my DFI BIOS, and tried VNB up to 1.6V. Nothing. (I pretend CAS5, didn't ever tried CAS6, but that would be ridicolous, and surely would pull down bandwidth results again).
Am I missing something, or is it normal, or do you have some other kit to suggest me?
I found, at a very good price (about 120 EUR), a PC2-6400 4-4-4-12 2x2GB Crucial Ballistix Tracer kit. Would that OC better than these Mushkin, on my DFI, in your opinion, or I'd better keep mine?
EDIT: I add just an another question: I would appreciate if you told me, in addition to comments on my RAM and those Tracers, what you'd choose between 450*8/1080 tRD8 and my 411*9/1028 tRD6, and why.
Thank you in advance,
Giacomo
