Which mem will give me 7500-8000mb/s?

[o27]

Hi all.

Looking to put together a new setup in the next couple of weeks.

My initial thoughts is to get:

Mobo: DFI Ultra-D NF4
Cpu: 3700+ SD or 3200+ venice
VGA: X800XL
HDD: WD 74gb

Ram: This is my biggest concern - i would like to get 7500-8000mb/s and just love the new G.Skill FF but they´re simply too expensive atm.
So what other choice do i have regarding the ram?
I need some ram that is "guaranteed" to hit 300/300+ ram

Your inputs is highly appreciated :D

I guess for "gauranteed" 300mhz you would be looking into some serious speed binning, OCZ Offers PC5000 I do beleive
Most G.skill LA kits hit 300mhz usually as well, my OCZ Plat Rev2's hit 300, but there hit and miss on 300mhz market, some others such as PQI and TwinMOS are able to hit 300, but pretty much the only sure thing of DDR600 is speed binned stuff, and the G.skill kits are a damn good bet as well

If you want 300Mhz but don't want to pay the high price of GSkill FF, then GSkill LE or LA will both get you there :)

why not some nice BH-5 ram

of course for low vdimm ya need some TCCD

[ben805]

the GSKILL PC4800 512LA 2x256MB kit is guaranteed to hit over 300, I had 4 pairs of these 512LA couple months ago and the slowest pair was doing 315 @2.5-4-3-7 1T :D newegg had them for around $145.

eva - have been looking at bh-5/UTT as well but since it´s gonna be a 24/7 rig i believe it would be more "stable" with 300+ TCCD low volts.
Unfortunately 2x256mb simply just isn´t enough for me - would get 2x1024mb if there were any good oc-sticks- but havent found some yet!
Ok then maybe i´ll have a look in the for-sale to look for som LA´s - is week 40 still the best bet?

I'd say go for bh-5. Just because it uses more voltage doesn't mean it's less stable. I've had better experience stability wise with bh-6 than I have with TCCD. The TCCD just seems to be really finicky with temps and voltage. I have found myself frequently having to lower or raise the voltage depending on the room temp, it's stupid. It might just be me though. :D

With my winnie at 260ish (260-265) and 3.3-3.5v my utt gets what Eva's does...between 7500-7600...and it's a 2x512 kit.

I'd personally take utt over tccd, and not worry about the voltage...Mine runs fine up to 3.6v without error (once I fixed a timing issue)...even though i'm using a 20pin psu and not using the jumper mod...although no more than 3.4+.03 - 3.5v is really useful to my set. I'm not using any unusual cooling on it either. Unless you find some tccd that will hit a good chunk over 300...utt will probably match the overall clock you'll achieve with the Diego better and give better performance...ala 260 (avg utt) x11 (highest multi on 3700+) = 2860 (somewhat average for SD's). With tccd you'd be forced to run the 9x multi if you run it at max, and pray the chips do well enough to get you over 2.7. If you can, you should check to find your max clock and then pair your ram accordingly...But I think something like Redline or VX would suit you the best IMO, if you have a dfi board or a booster.

Plus, if you ever use better cooling in the future, you have the option to use a divider to scale the clock without losing mem performance. With tccd you're basically forced to use 1:1...because using a divider in most instances will cause the HTT to crap out from being too high.

3700+ and utt would be what i'd do. But if you go with a 3200+ venice, either utt or tccd could be a good option. Either running utt with a 166 divider and 9x multi or tccd at 1:1 and a 9x multi. If you go with the tccd, surely there are many great options, but a good set that's cheap is PDP's PC3200+XLBK. They're the cheapest i've seen, and i've seen quite a few peeps get over 300 with them at 2.5.

just my .02. I hope you find something that works out for ya'. :)

for 24/7 I'm running my 512LA at 306 @2.5-4-3-7 1T with only 2.7v prime95/occt/memtest/superPI 32M/3d loop stable in this summer heat :D :D if 2x256MB ain't going to cut it for you, then consider the PC4800 1GBFF....it's also guaranteed to hit 300. But if you're willing to use the memory divider or have higher multiplier...then any UTT/BH should do it, I have both the Gskill TCCD and Mushkin Redline, personally I prefer to use my TCCD for 24/7, and the Mushkin Redline for superpi race and 3D benches ;)

it also depends a lot on proc. speed, you ma need a good oc to get 8000mb/s

[M.Beier]

Hey there fellow dane, ø27..

Nearly all mem can reach that BW, even micron ;)

But best mem would properly be G.Skill 4800FF, 4800LA, 4400LE, OCZ VX4000, Gskill 3200GH, Mushkin redline, good-old-BH6, BH5..

But lot of it depends on your memcontroller, spoke with SIOUX earlier - He told me that his old FX allowed him running 315 mhz 2,5-3-3-x, while his new San Diego "only" allows 2,5-4-3-x at that speed... RAS to CAS is the most important timming when it comes to A64 - so it was a major drop futher a FX core give quite more performance than winny / SD :)

Anyways - the G.skills will insure you a great BW ! - But they aint great for to bench with - as a due of the high RAS to CAS latency ;)

Ballistix needs ALOT of vcore to perform very well... 3.8 to go passed 260 mhz with tight timmings, and when even at 2.8v they're burning hot, you sure dont wanna go to 3.8v without some additional cooling ;)

And I've only reached like 7600 MB/s.. :( - Could properly do 7777MB/s in win64bit - but dont wanna install that again untill the lame bugZ er fixed..

I've actually heard lots of info to the contrary... And 3.8V? Are you sure that's right? I didn't think Micron -5B G could stand that much voltage, no matter what the cooling. :stick:

I would personally go for some new BH-5, like OCZ's PC3200 EL Gold. It's reasonably inexpensive and seems to be doing 255-260 (2-2-2-5, of course) without too much fuss if you feed it some voltage. It might not get you the bandwidth of ultra-expensive TCCD, but it'll save you some money and be just as fast in the end. :fact:

[o27]

wow thanks for all the great inputs guys :thumbsup:
Hmm seens most of you guys are leaning towards the UTT stuff - then i´ll do some more research on those - as it seems they´re reasonably better priced than high qual TCCD 300+

Hehe, no dont wanna give them that vdimm for 24/7 usage, only for doing some benchies :) - Give 'em 3,0v for daily usage 2,5-2-2-5 8-10 :)

ø27, yeah... The price is a bit more discent :) - I think G.skill PC3200GH or Mushkin REDLINE would be the best buy when it comes to price... If your fast you might be able to order some with SIOUX, he'd just to order some REDLINE I think ;) (Redline's the ones Charlie got at 1,5-2-2-5 @ 270mhz or such eXtreMe speed :))
