Have been running this ul since it first came out, but looking for a little more performance, possibly the new 8500. Does anyone know if the 8500 OCs as well as the 8000ul or if the same D9s are used.

wait a bit more new ics are coming then you'll see a nice improovement
I'll recieve 4*512 8500's in a week or so. gonna clock a lot, so ill come with some results then.
proth, I'd hang on to those 8000s for the time being. Until we start seeing some results from the stuff coming out, it may still not be as good as the D9s for tight(er) timings even though the default speeds are increasing.
It seems 8000ULs are starting to pop up here and there again...I ordered a pair and they should be here today. Anyone have any idea if they are still D9s or have they switched to some "comparable" ICs? My Mushkin XP6400s are D9s, so I was hoping they would play nice together for 2GB total with pretty decent timings, but now I am not sure what the 8000s are going to have and I really don't feel like pulling the spreaders on new sticks to find out.
I am really kinda anxious to see the new stuff too...particularly what the Corsair 8500s will do in "real life". If they can do like DDR1100+ @ CAS4 with upped voltage, that would be nice. OCZ is listing some DDR1000 CAS4 now and I saw DDR1100 CAS5 from them, but no word on their site about it yet. Mushkin seems to really be dragging their feet with their new stuff and they're really the ones I was waiting for.Quote:

I gave the XP6400s a test to see how they are holding up after 8+ months of abuse from me and they seem just as strong or stronger than when I got them. I didn't try max, so that's still pretty much what is in my sig, but this was what I got just today. I was too lazy to bump the voltage further to see how far they would go at these timings, but this was it at 2.60V...definitely the tightest it's ever run at DDR800 (does up to DDR1066 4-3-2-4 @ 2.65V). I am dying to see if the new stuff bumps this up performance up...

Looking forward to seeing the results of the 8500s!
Good luck with them Steensen. Hoping for you @ DDR1100 4,3,2,8Quote:

Don't need 8500s for that, but that would be SUPER impressive on 2GB and 4 slots to boot. I'd sell all my D9s for 2GB that would do that ;) I finally had some time to test out my new 8000ULs:Quote:

@ 2.55Vddr DDR1100 4-3-3-4 benches SPi's w/o errors. As soon as I get my DI tube back, I'll do some 5.7-5.8GHz SPi's, naturally ;)
This your 8000UL ? ehmm Fantastic :) :) Versi ? 512 x2 or 1G x2Quote:

I am happy with them ;)
@ Hazzan, missed it: 2x512MB. I don't think they have any 2x1GB ULs ;)
Damn Boostdevo, reminds me of my old drag racing days, always getting beat by a fender, or maybe a door with that 570 @ 4-3-3. Super timings there man. Time to pull out the tube and trim off another 30 seconds of SPi32m for OCF.
This was what I was able to score (with minimal tweaking) with my system Monday night GMT+1
The 2001Se I got tweaked up to 32290.
Enough OT.
These 8500 are no good. :(
I cant eaven get them to run 1066 5-5-5-15 with the 0101 BIOS, but they are 3D stable and 32M stable at DDR1000 5-5-5-15 2.3Vdimm (like in pics attached). They freese memtest86 in test 5 around 25-40%, if they are clocket any further than DDR2-1000. :mad:
Perhaps it's just me that's no good tweaking my memmory, but these 8500 RAM are no good IMO. Haven't tried with only 2*512MB yet (haven't got thetime).
Steensen : Give it more voltage and test 512X2 ?

Close competition keeps you focused ;) I might run the tube this weekend and stick the 930 (15x) or 550 (14x). Looking forward to your results on voltage!
@ Steenson, sounds like a bad pair maybe if they won't even run at specs? How much voltage are you running on them?
@ Steensen.. Problems here also with 8500. Maxes out @ around 1180 5-5-5, 2.7v doesn't help. Only SPi stable so far.
@ Ross..Got ya' by 2. Still 8000ul. 8500 seems to ...uh...SUCK. Ran these @ 2.6v

Very nice proth! That's actually really excellent for 2.6V. I'll have to see if I can squeeze a couple more FSB more out of it or maybe try lowering .1V.
That stinks that much extra voltage doesn't do anything on the 8500s...was hoping for some big speeds out of them considering CAS4 isn't an option.
Just be careful with them D9s there buddy. I don't think you will find another pair. :) I may have a few more MHz if I get some cold air back on them. :stick:
I meant trying a lower Vddr and see if that's all it needs there. It was at 2.7V for the 1140 I had. I have the XP6400s as a back up, but I was thinking about selling them so I'll make sure not to kill the 8000s ;)
Haven's moded My MoBo, so can't give any more than 2.4Vdimm, wich makes no difference.Quote:

Maybe I should start getting my MoBo moded, so the Droop, TT and VDimm is no problem any more.
I didn't see any differency in the 8500 going from 2.3v to 2.6v, sorry. But I understand ever pair is different so maybe you will have better luck. If you have the P5WD2-E, you MUST doo the droop mod above 4.5GHz. It works like magic, but is a little tricky because of small SOT parts. The Vdimm mod is quite a lot easier. Good Luck with it. You have a very nice system
Steensen, that's just not right. I mean they are not even running at rated specs (DDR2-1066 5-5-5-15 @ 2.2V). It should not be up to you to add more voltage and mod the board on top of that to do it. I'd mod it anyway since it will be beneficial down the road, but it sounds to me like more Vddr isn't going to help in this case.
If anything is a legitimate RMA, those sticks are. There's no telling if you'll get sticks that are any better just swapping them under RMA. You might want to see if you can do a return RMA (or return to where you purchased as defective) and look for something else?
Lets see the Benchmarks for both these chips so we can actually compare.
Proth THX m8, But I haven't got the nerves to do the mod myself. :(
But yet again I'm only running 4.2, so it's close, but no cigar. ;)
boostedevo That's what I thougt too, but yet again, the Dimm mosfet can be a bottleneck, and not capable of supplying enough juice to the dimm's, and therefore they cannot run the specs.
Try out two dimms this weekend I think, otherwise, I'm going to RMA the dimms (all four of them), to see if that helps.
Just weird that the dims runs super stable at 1000, but 1010, then they want complete a memtest86. :( :confused:
Try more MCH voltage, could be the board not the ram thats failing.
Thx for the advice, but they still wan't do 1066 when I set it for DDR800 devider.Quote:

Wow, you guys are on top of things in here. If you're having problems running 2 modules at 1066 at 5-5-5-15 at 2.2V, we'll RMA them no problem.Quote:

As for top end, we see a lot more headroom in the new Microns than the old fatbodies, and the old fatbodies were awesome. I'm sure you've got active cooling on them and on the northbridge, so I won't even point that out.
Seriously though if two of the modules fail at 1066 @ 5-5-5-15 @ 2.2VDIMM, send them back to us and we'll replace them with something faster.
Redbeard posted a possible issue on slots. If you have a multimeter and think the board might be the issue, I'd measure the DIMM fet or better yet, the memory side of the coil, and see how that compares to your BIOS setting for Vddr. If it's .1-.2V lower, that could be a problem and it would be the first I've heard of anything like that. My unmodded board was obviously a little lower than set, but just a couple hundreths of a volt.Quote:

Really?? As in the current ICs in new 8500s or a new batch coming in? Is the CAS4 issue (ie. none) just from programming?Quote:

Thats the fact Jack! I was REALLY hoping the new ICs would cough up a solid DDR2-1100+ @ CAS4, even if it took a little more voltage. See anything like that in the near future? :DQuote:
and the old fatbodies were awesome
Corsair is always on the ball with service...to see you pop up in the forums on you own accord and offer to handle Steenson's issue is just awesome! :toast:
These chips are owning. Mobo is P5WD2-E.. Mobo has vdd2 mod but rams are only at 2.3v max.. I'll push further later this week..

http://img88.imageshack.us/img88/1835/850010986uh.jpg
They're not owning yet, but damn close :) Congrats! Impressive for 2.30V...did you measure it on the board to verify you didn't accidentally leave the pot turned up because that's a complete 180 from the 8500s I've seen so far? Or are those 8000ULs...you didn't specify ;) That's like D9 type speeds/timings with hardly any voltage. I'll be curious how high you can carry the CAS4 with voltage. If it's the 8500s and you can get close to DDR1200 CAS4, I'll still have hope for them :D Good luck and keep up posted!
See my sig. Then you see I've got water on most of my setup, including NB (That sits first in the NB/GFX/HDD/Mosfet loop), so temp on NB is no prob.Quote:

Mounted G-RAM cooling profiles on the mosfets not cooled by water, and the Dimm mosfet doesn't seem to become warm at all, so it should be wierd if the dimm mosfet is the problem.
Wich Mobo did you have problems with 4*512MB in?
Nice to know about the black vs. yellow slots. Thx m8.
If I get anny problems with 2*512MB, then I'm gonna quote you to my dealer, so that i can/will send the dimm'sfor RMA.
Where is that messure point? (please show on a pic.)Quote:

Measure either the center leg on that fet or that solder point on the coil. The coil is better (would show least voltage) and safer...plenty of people have slipped and shorted things trying to measure those short legs on fets :)

THX. Looking into it later.Work calls.
I'm really not interested in benching anything now that have to run under 5GHz with the warm weather and I don't usually don't post any lower scores that posted before. Someday my Chilly1 SS will be here, hopefully before Conroe hits the general public.Quote:

Ran memtest on the 8500 and didn't get them stable to around 1050 @ 5-5-5. Tried each stick seperately and they are about the same.
Weird thing is they only run 5-5-5. Can't even run 4-4-4 @ 1000
Also did a Vdimm mod and running them up to 2.7 doesn't help. Looks like Absolute is getting there...
Proth Sad story. Gonna test mine later today.

Will put some more tests later..
I'm not familiar with the CAS4 issue you're mentioning. We've got them running in the labs at CAS4 at 1000+, sometimes higher, though I can't really give out too many details on that. My suggestions with these ICs for best performance so far:Quote:

-High voltage
-Keep an eye on tRCD, unlike the older fatbodies, where you could run 3-2-2 almost as fast as 3-3-2, these ones are much more susceptible to the tRCD being the limit. We see 4-5-4-12 hit almost as high as 5-5-5-12 with the same voltage. If I was trying to hit 1100, I'd be at 4-5-4 and 2.4 (or higher) volts.
We use the P5WD2-E board with a 955 processor and air cooling on the northbridge, 0401 BIOS, and we test everything internally at 2.2V. We also use RST Pro2 cards for stability testing, which correlate pretty well to Windows stability.
If you want shots of our BIOS settings for our internal testing I can take those later, but I've got lunch to eat right now.
I've just been testing My dimm's, and 2*512 ran 1066 5-5-5-15 2.2Vdimm through memtest (diden't wanna go through heavy stability testing), without a hitch.
CAS 4 was possible with 2.4Vdimm 1066, but at 1080, they maide errors in memtest.
As soon as I put in the second pair of dimms, no matter witch pair sits in witch slots, My dimms will not run 1066 5-5-5-15 at 2.4V, so neather at 2.2V.
My MoBo is not moddet, except for watercooling on NB and mosfets, and cooling profiles on most other mosfets (those in between the capacitors, between edge of MoBo and socket, these get quite hot at full CPU load).
All these test has been done with the 0101 BIOS, so I guess, that it's time to flash to 0401.
Has anyone tested the 0422?
Redbeard Have you been able to get 4*512MB 8500's to run 1066 in your lab P5WD2-E MoBo, with the 955EE?
We haven't tested 4x512 successfully yet as far as I know, we qual things in pairs right now, but I'll throw some on a board and respond with results tomorrow.Quote:

Redhead, my 8500 is just come from corsair. They are very sensitive to 2 timing .. in 3-2-2-x they cant hit as 5400ul or 8000ul but at 3-3-3-3 they made 840 ( 8000ul hit 790 with the same conditions ). 2.3v 4-4-3-4 @ 1100MHZ no active cooling on memory or northbridge. (8000ul hit 1040 at 4-4-4-4 2.3v) .. also i gave up to 2.8v to 8000ul .. I was planning to give up to 2.6v.. But now I'll be more careful about the voltage because of this heat problem.Quote:

Excellent results Absolute! Is that 4-4-3-4 @ 1100 stable/error-free on tests? That would be impressive on 2.3V. If you can pretty much keep those timings @ 1200 with upped Vddr, I may have to give them a shot. Nice idea with the breadboard for the mod BTW ;)Quote:

Yes, I am a dolt, LOL. I was thinking along the lines of memtest, but any benches a little newer or tougher coming up for the next round of testing? PCMark04 is much tougher to pass with a score than 02 and SPi 32M would test them pretty well. Close to the limit, I can pass SPi 1M at speeds/timings that will error after 1 iteration of 32M. If it's really on the hairy edge, it will pass 1M and not even 4M ;)
Thanks again...looking forward to your results...
I want some new ram, sould I go for: 8000UL or 8500 ?
When I look at the results so far there are close, but 8000UL has better timings.
And what's the max or min voltage of Vddr ?
^^^ I know...very confusing man. But I really hope to get what Abolute 0's performance is, if I get those PC-8500 :) I mean 540+@4-4-3-4 @ 2.3V is really super clocks.
8000ul is End of Life and replaced by 8500, Doubt if you can find them anywhere.
^^^ Too bad no 2GB modules with any :(
I found 1 store, selling 8000UL for € 270,- ( sold out :( )Quote:

Hardware:
P5WD2-E w 0402 BIOS
955X processor
4x CM2X512-8500 (2.2V @ 1066 @ 5-5-5-15)
Fan on northbridge & mosfets, fan on RAM, Nautilus 500 on CPU
Silverstone Zeus 650W PSU
Both sets of modules pass just fine when there's only 2 modules, but up it to 4 and the system is less than 100% stable. Since 1066 isn't an official JEDEC spec and isn't supported by Intel yet officially, I am not surprised. I'd imagine that we'll see a 1066 in Q3/Q4 this year if I had to guess, and probably 1200 next year sometime, but anything after 1200 would probably be DDR3.
This is all hypothesis by me, though, I am not privy to the actual plans of Intel and Jedec and now, I guess, AMD's determination on what they're launching AM2 at, speed wise.
Maybe you could try a little higher chipset voltage (if you didn't already do that)Quote:
