OCZ 2x1gb PC4000 EB.... My results so far..

[Radelon]

I received this kit on Thursday and was very excited to have a new toy. First night the highest i could go to windows was 270. But now after playing for a few days, here's my current numbers.

[Trice]

Nice man, I have the same sets (the ones they just released right?) what volts, bios, and dimm slots are you using with them?

[oasked]

Thats insane! :)

What volts etc are you running at?

[infiniti029]

nice, keep us posted with more tests at diff settings.

[dnottis]

haha they must love the winnie memory controller

[Vapor]

trc should equal tras + trp....so 9 in this case

[Radelon]

Orange slots, 2.65v, 7/4 BT Bios.

I'll give that a shot jason......any other things you guys want me to try?

Oh yeah, this is a 3500+ Venice.... I haven't updated sig in a while.

[Okda]

keep us updtaed with ur results please

[tomati]

Nice shot there , 285 3-3-2-x , real good.

[Tony]

nice but trc=10 is yukk try 7 you'll gian like .5s+ in 1m alone from trc=10 to trc=7 maybe even 1 full second

jason...setting TRC to 7 will gain nothing here, the only thing you actually may gain is a lower overclock and instability.

When setting the follwing timings you will want to do the following.

Applies to TRC, TRAS, TRFC.

Set to highest setting, work down slow till an increase in bandwidth is seen, make a note over the range of settings what gives the highest bandwidth then set the highest setting within that range.

So, say TRAS 5 to 10 give the best bandwidth with 11 dropping 80MB/s, setting 5 will close the open pages quickest but setting 10 may actually yield the most speed as nothing has to be reopened and re read.Setting 10 would be best.

TRC may have the same performance from 7 to 12, setting 7 will actually dial in instability for no gain in bandwidth so 12 would actually be better.

TRFC is not as criticle and for the lazy sods like me setting 24 is actually ok but it is actually best to set TRFC 2T higher than TRC so TRC at 12 and TRFC at 14 etc etc if you can, some times 3T is needed.

Hopes this clears things up for you all.

[Tibu]

Wow this stuff is very good. I can't decide between these and Crucials Ballistix :stick:

[Radelon]

This stuff is a blast to play with. With 2.5-3-2-6 I was able to hit 255 sticking at 2.65v. This stuff is probably the easiest ram to overclock. Tref is a huge thing with this ram. For example with TREF of 4708 it only went to 270. I changed that and now i use like 1536, 1552, 1560 which put me in the 285 range. I'm still really just trying to feel this ram out before I do 3d stuff. In sandra, unbuffered Mem Bench is like 3600/3600 but the ram feels so much faster than even TCCD at 310. I would definitely recommend this to anyone looking for a great 2gb kit. Stay tuned in the next 2 days I'll try and get some 3d benches up.

The TREF really took you from 270 to 285? I played with it but obviously not enough if that really let you go that high. Can u 3d bench at 285 though?

[Radelon]

Honestly haven't really tried to 3d bench that much I know it could be an issue so I'll give it a shot.

[Radelon]

3d benches at 270.

[tomati]

3d benches at 270.

nothing more ? or not enough time to try ?

What was the formula for working out what tref(s) are best to use?

[F@TMAN]

any experiences with ballistix, Radelon? Are you in a position to compare between them and ur EB kit? Purely on performance, though...

[Radelon]

As for time, I'll have time tonight after work. TREF, you just try them all, within minutes at 270 you'll find ones that'll make it not work, just eliminate and keep moving along, eventually you'll find the ones that work the best. As for ballistix, no I have not had the chance to try them out so comparing is out of the question. I guess the real thing we should notice is the fact that Ballistix are hit or miss, some are great and some are not. With this EB, consistently everyone is hitting over 275. More to come.... g2g work....

[eva2000]

Can confirm Radelon's findings... just got my 2x1GB OCZ PC4000EB Plat around 8+ hrs ago (so very early testing)

http://www.fileshosts.com/memory/ocz/2GB_PC4000EB/thumbnails/thumb_PC400EB_009.jpg (http://www.fileshosts.com/memory/ocz/2GB_PC4000EB/photos/PC400EB_009.html) http://www.fileshosts.com/memory/ocz/2GB_PC4000EB/thumbnails/thumb_PC400EB_022.jpg (http://www.fileshosts.com/memory/ocz/2GB_PC4000EB/photos/PC400EB_022.html) http://www.fileshosts.com/memory/ocz/2GB_PC4000EB/thumbnails/thumb_PC400EB_025.jpg (http://www.fileshosts.com/memory/ocz/2GB_PC4000EB/photos/PC400EB_025.html)

Just jumped straight into deep end and set ram at 10x285mhz 3-3-2-8 7-14-2222 at 2.64v vdimm and tried a bunch of TREFs and eventually found these 3 seem to produce the least errors

memtest86+ test #5 loop

TREF
1552 = 1 error at 38th pass after 59m 46s

1560 = 5 errors in total after 44 passes at 4th, 8th, 11th, 22nd and 32nd pass after 1hr 09m 18s

1536 = 11 errors in total after 29 passes at 6th, 10th, 13th, 17th, 20th, 23rd, 24th and 27th passes

so seems TREF 1552 is one to work with .. now to tweak the rest of the advance timings and voltages etc :)

For comparison for memtest86+ v1.55 reported bandwidth at

10x285mhz

2x1GB Crucial Ballistix PC4000 Tracer at 3-3-3-8 7-18-2223 1T at 2.76v = 3181MB/s rock stable in windows

vs

2x1GB OCZ PC4000EB Platinum at 3-3-2-8 7-14-2222 1T at 2.64v = 3377MB/s 1 error in memtest test #5 as shown above - so need ALOT more time to tweaking to see how it goes in for stable speeds but very promising as it's as easy to oc as Ballistixs!

Not 3d benchable at 275 for the people posting..so far only FX chips can actually 3d bench at 270+ and a few people with winnies.

A few of us with San Diegos can run 280 Mhz in memtest and Super PI but max 3d benchable is 260 Mhz with Sandy cores. My venice let me 3d bench at 267 Mhz...

Great work!! Saves us alot of time!! Thank u!

A few of us with San Diegos can run 280 Mhz in memtest and Super PI but max 3d benchable is 260 Mhz with Sandy cores. My venice let me 3d bench at 267 Mhz... I will try lowering the TREF and see if 3d benching is now possible. Will report back

I just saw you have an FX, those are the only memory controllers than can 3d bench over 270 consistently. Ill still try and report

[eva2000]

remember it's cpu mem controller dependent still heh but so far Radelon's winnie cpu TREF applies to my FX-57 sandy mem controller so far

[dnottis]

Well I broke 260!!

3dmark just completed at 262 and its running 265 x 11 now!! Sweet, thanks again for the tip!

It's actually a 3500+ Venice core. This ram is pretty amazing, I think with all of us working together we can get these stable in 3d a lot higher. I just knew once people started trying the 1500's in TREF that the numbers would go up. Actually try TREF's in the 1500-1800 range. Maybe on weaker cores we might even want to try below 1500. These are all things that need to be tested and I'm hoping I'll get to try them tonight.

[Radelon]

Power went out last night during my testing but I will get the 3d benches up soon..... sorry for the wait guys...

seems 10x280mhz 3-3-2-8 like OCZ said stresses mem controller more and 3dmark2003 froze at GT1 with 2.64v vdimm, froze at GT4 with 2.69v vdimm and 3dmark2003 fully passed at 2.69v vdimm and at +0.25v more vcore to the cpu but the score seemed lower than usual.

But 11x274mhz 3-3-2-8 definitely works :)

Ran GT1 and GT4 (both most stressing on system) in 3dmark2003 in 40 loops @1600x1200 resolution with no probs

then did these

man this is a great 2GB ram.... i just order one from newegg... hope i can max to 300 lolz

[styyn]

man this is a great 2GB ram.... i just order one from newegg... hope i can max to 300 lolz

I just checked Newegg and they didn't have these sticks listed. I saw the PC4000 EL's, but no EB's. If you're sure you ordered EB's could you provide a link? If not, might want to cancel that order ;)

[Radelon]

Sorry for the delay, been a long week. Here's my best settings for 3DMark 2003:

Bench Setup:

3500+ Venice
DFI NF4 Ultra-D 7/04 BT
2x1gb OCZ PC4000 EB
XFX 6600GT 560/1140
etc.

[Radelon]

And for 3DMark 2005:

http://home.mchsi.com/~radelon/05270.gif

[tomati]

Oh well , 270 under 3d app , that sound to be a good pair you catch there.

[Radelon]

They will 3d bench both 2003 and 2005 up to 280, but scores drop. and 2001 is weird, no matter the setting it'll lock..... but everything else is 100% stable.

[mcoleg]

I just checked Newegg and they didn't have these sticks listed. I saw the PC4000 EL's, but no EB's. If you're sure you ordered EB's could you provide a link? If not, might want to cancel that order ;)

yep, i was looking for those myself... any linkies?

[guess2098]

yep, i was looking for those myself... any linkies?

i saw it wrong.... :slapass:
i found out yesterday and canceled it... hehehehehe
then i ordered from manora... how to spell that??

thx for the notice :)

[Radelon]

On a side note 11x255 with 2.5-3-2-8 is faster than 10x272 in 2003 and 2005.

[mcoleg]

i see. bummer...

[kamongear]

Nice sticks you got there.

[Radelon]

I guess I needed to be more clear 10x272 results in 9948 and 11x255 results in 9998. But there's also a 80mhz gap in cpu clocks. At 10x280 I think it would be a lot faster than 11x255. Nice thing though, the ram really likes being at 2.5-3-2 in the 250-260 range so it gives you plenty of options to match your cpu.

[eva2000]

Radelon try 11x252mhz and see how it compares to 10x272 :)

[Vapor]

I'd like to see a comparison at equal CPU speeds...247x11 and 272x10. :D

[eva2000]

Whoops calculated it wrongly 11x247 - i'm guessing 10x272 would win then...

[Radelon]

[goreblast]

Am I not correct in saying that as the 3DMark series has advanced from 2001, through 2003 and onto 2005 they have become less dependent on the system as a whole and more dependent on graphics cards. Therefore 2001 is a better indicator of overall system stability than either 03 or 05.

This will be why you are able to bench both 03 and 05 but not 01 without crashing. You would be far better getting it stable for 2001 if you are after a highest stable overclock rather than a screenie.

[Radelon]

But I found 2001 was a driver issue, it runs fine now, Just don't wanna switch drivers, just for higher 2001 scores.
