wtf is that last XMP profile ?
4-1-1-16 31T 4.55v :ROTF:
static read/write helps tad more bandwidth and lower memory latencies but can quickly add to memory/system instability as well :)
TB is performance level or tRD AFAIK hehe
hmmm gotta try that out, thanks :toast:
ill check again but im pretty sure that when i played with transaction booster it only changed perf level. i prefer to change it in windows tho, so i left it untouched :D
Changed from E6600 L709A958 to E6850 L723A347 cpu for more tests.

Latency result bug in Everest ? When you run it individually it's lower latency then via the tool ?

Now to max out my E6850 on Corsair Nautilus 500 water cooling, seems it hit same max for 32M as when on Blitz Formula with same cpu cooling - 4104Mhz at 1.632v on Blitz Formula in 22-24C ambients while 4104Mhz at 1.672v on P5K3 Deluxe in 28-32C ambients (no more winter cool nights in OZ :( )
Didn't try lower than 2.0v vdimm for this session as I wanted to make sure memory wasn't the weak point for now.

Nice work and nice benches, nice RAM as well!
We appreciate the SS :D
Yip as usual Goerge excellent testing and review always enjoy your posts nice one.
Sigh, my TeamGroup 1600's clocks to 870MHz with the exact same timings as your sticks (7-6-5-15) but I can only get 8K on Sandra buffered. Board is a Gigabyte P35C-DS3R. The board doesn't offer 1T command rate though, but surely that can't make a 2K difference?
thanks glad you like :)
also slightly depends on cpu clock frequeny so you would get higher sandra buff at 9x400FSB 1:2 than you would at 7x400FSB 1:2
Awesome, would save me having to run both methods and screenshot them side by side hehe

Sorry for the massive pic!
Just thought I'd show you what I'm facing here :( Will pop my E6850 that does 550MHz in tonight and see if I can get a better score.
Thanks Eva.
andyddr, what chipset voltage are you using?
try more and see if that helps

Not sure what's going on with your board as i never used that board. 1T gives me an extra ~200MB/s memtest86+ v1.70 bandwidth over 2T so no it won't be reason for 2000+ MB/s difference in sandra bandwidth I don't think. What cpu speed was that 8k buffered run at ? 3050Mhz ? try at 9x 440FSB or higher
Thanks for the input guys. Seems like the problem here is infact the motherboard's poor optimization for DDR3. I've tried the E6850 @ a higer FSB and only scored 300MB/S more. Add to that I cannot set to 1T in the bios. Should have done a bit more homework on this board (X-bit has an article up on the poor performance I just mentioned) before I bought it. See Newegg has just added X38's to their pricelist though. Great timing!
ohhh your on a hybrid ddr2 ddr3 board right?
Yeah, those all suck afaik... but i didnt know they perfom that much worse at the same clocks 0_o weird
