DougLite said:No problem getting them at 2:30 this afternoon in Indy/Fishers. The ones I got have Nanya chips on them, SPD of 2.5-3-3-7 @ 166(2700) and 3-3-3-8 @ 200(3200). They pass SuperPi 1M w/ 2.5-3-3-7@ 196 MHz 2.8V. They hold the same SuperPi 1M time (31s) as my pair of 512MB sticks of BH-5. They bench 48.5ns latency in Everest, while my BH-5 bench 40.8ns. Awesome deal.
vibe said:Besides reducing latencies, can you tell me how high these will go on 2.8v?
Can you get them to 225mhz when you use a 166mhz base (or otherwise)?
My high density Advance Modules will do 225mhz max on 2.8v.
Thanks!
ps. no one is having any trouble running them in dual-channel right?

Dual channel just fine When running with ClockGen they crashed windows between 240 and 250 so DDR400 or 1:1 doesn't look very likely since i run my 3800 X2 @10X275.
vibe said:Oh very sweet, thanks for the info.
BTW what voltage are you using on your X2 for 2750?
I can do that but only at 1.55 which is too scary to do for anything but testing.
If I can do 230mhz in my Tforce, my Advance Modules are going on sale here or ebay too... the extra 5mhz means I can run my x2 @ 2650 easier.
I would never expect value ram to do 240-250mhz but 230 would be awesome.
I suspect I will be able to do 1T again once I get external video.
Onboard video on the Tforce seems to make 2T manditory on all ram.
cherrypik said:Downers Grove had a ton. My buddy and I both went into the store twice. He's running all four in his computer and I'm running just one set. I might sell the other to my buddy because my Asus K8v-SE Deluxe board is a POS.
vibe said:Any more OC reports for this ram?
Mine should be here within ten hours, so I guess I'll know myself soon enough.
I see newegg/chiefvalue are selling the 1GB kit of these for $80 so that's a great feeling...

Don't raise the voltage. I was flunking memtest test 5 until I set DDR voltage ftom 2.8vdc to auto
vibe said:We have extremely similar cpu's and setups (except I have onboard video and 2T)
I'll try 10x275mhz with those timings tonight. I can hit that with 183mhz on the corsair.
Can you run a superpi 1M with nothing else running and tell me what you get?
are the nanya chips better/worse than the corsair chips? i got the nanya ones too.renegade44e said:32.5. I have Nanya Chips, though
Soymilk said:are the nanya chips better/worse than the corsair chips? i got the nanya ones too.
vibe said:Okay - I take it all back. This is pretty good ram for the money.
After 12 hours of running, it's doing better, apparently there was a "break-in" period.
I was able to get cas 2.5 all the way up to 230.6
Actually I can't get any higher than 230 no matter how I relax the latencies but this is still 5mhz faster than my advance modules and cas 2.5 to boot. I was able to lower all the other timings very low without any ill effects, though their change was minimal to performance gains.
230.6mhz 2.5-3-3-7 >2744 cpu 2.5-3-3-7 >

renegade44e said:I'm at 230 but I'm also at 3-4-4-8 AND "1T". 1T really kicks ass over 2T. If you have the nanya chips do not up the voltage, I'm using Auto. I used 2.8 for a while and itt was counter productive. I'll have to try CAS 2.5 when i get a chance.
Soymilk said:how important / much of a performance increase is there in cas 3 vs cas 2.5 vs cas 2? is cas the most important of those 4 timings? it's the only one that anyone ever mentions.
vibe said:Okay I have found the sheer limits of the ram.
You can get CAS 2 if you are willing to underclock to like 180-190mhz but not worth it as that kills your entire bandwidth.
The great news is that you can do 2.5-3-3-5 up to 230mhz stable!
Memtest86+ reports the ram bandwidth as 2624kb/sec at those settings
(a number so high I almost fell off my chair, I hadn't seen over 2500 previously)
here are the tightest settings at 230mhz I could get (using 2.8 volts)
2.5 tcl
5 tras
3 trcd
3 trp
2 trrd
7 trc
13 trfc
2 trwt
(2T, I have onboard video)
Sisoft reports 4700 memory bandwidth when I run it at 229mhz (2745mhz cpu)
Strangely it also reports single channel and 1T, both are wrong
and proven otherwise by the benchmarks themselves.
