anyone try the ram at hardcorecooling.com

[JNav89GT]

Was looking at 2x512mb of thier PC3700
called tech and he said they were micron vdata chips. He wasn't sure of ns rating but said the sticks were tested by manufacturer to run at pc3700 at cas2.5 3:6:3

what u think

[JNav89GT]

well decided to be a guinnea pig
ordered 2x512mb PC3700 ram
only like $210 or so shipped

[TerroH8er]

sweet.. let us know how it goes

[JNav89GT]

sure will. would be sweet if this is actually good mem. My gut tells me not to get too excited tho. But if it runs in the low to mid 400's at tight timings I will be happy. For $103 for 512 it's a good deal.
I'm starting to see a difference in games and load times going with 1gig over 512mb so moving all my rigs up to 1gig o ram is getting pricey, but if this memory proves descent that will help out :)

damn thats cheap. i paid more than that for 512mb xms3500 in january....

V-data and A-data chips are super fast. I'll be intersted in your results.

Note the 2nd persons memory speed and what he hit: http://holicho.lib.net/wcpuidv3/wcpuidv3.htm

well I hope to get them by the weekend along with my new NF-7 ver 2.0
will prolly just vdd mod it before installing. and go to town then

I need to redo the vdd mod on my Epox 8RDA+ b/c with the static resister at 680ohms I get like 1.84vdd and it's good to about 210-215
but I think if i can get it to like 1.95 i can get 220's out of it. I got 2x256mb twinmos that will do mid 220's and one 512mb corsair pc3500 in that sys with the 512mb stick in the 3rd slot(the one farthest from cpu) so I am running 1gig at dual channel and hopefully balanced with the 2 256mb dimms in the 1st channel banks and the 512mb in the 2nd channel bank, does this make sense. :)

then the new ram will go in my nf7 and my older corsair pc3200 512mb C2 dimms will either get ebay'd sold or stick in the NF7-S that I plan to get next week as well. Bringing the in house NF total to 1 epox and 2 abits to prolly kill shortly :P

yes a-data ram rox. they are the first to use the new ch-5 winbond chips. :)
here are the specs :
Features:
- Chip on board: Winbond W942508CH-5.
- CL 2,5-3-3 (default SPD).
- CL 2-2-2 (tested).
- 400MHz DDR.
- Package: 184-pin DIMM.
- Unbuffered.
- Alimentazione: 2,5V (± 0,3V max).
- Serial Presence Detect (SPD) EEPROM on board.
and here is a thread about it : http://www.amdforums.com/showthread.php?threadid=215281

and you can buy them here http://www.swzonesystem.it/product_info.php?cPath=1_16_42&products_id=133

well some initial teething pains. Having probs running 200+ fsb. Haven't tried lower as there is no point really. Might be settings, but will have to reserve judgement till later. Price is right, but my 2 sticks aren't capable.
Test system. Epox 8RDA+ vdd 1.9v tested stable to 215+mhz fsb
1st tried dual channel with 2x512mb PC3700 memory settings cas2.5 3:6:3 timings. 3000+ errors in 3 runs of memtest86

took out 1 dimm-same result. Switched dimms out. 2nd dimmm much better but still about 30-40 erros every pass. This was at 200and 210fsb settings. At 215 errors would increase. 220 was a no go. Tried 2.5 and 2.63vdimm and briefly 2.8v. Didn't want to try higher as would void warranty. No help with higher vdimm. Didn't try slower timings as what is the point, it would negate any benefit over my Corsiar or Winbond that will run 215+fsb at these timings. I would think that if ram could run 233mhz/466/3700 that it should be able to run at 200-210fsb at tight timings, much less at the same timings it's rated for. :(

[JNav89GT]

well they at least get an A++++++ for customer service. Tech gave me an RMA and advanced replacement. Stated the current dimms they have use winbond chips with next shipment using the vdata ones. Not sure which are better. Hopefully next set will work :rolleyes:

[JNav89GT]

well I may reverse my opinion of the ram. Got the abit nf-7 S(payed for non S but got the S from excal) ver 2.0 and although I haven't passed memtest, I decided to just let board load OS(from old Epox 8RDA+ install) and fux with it some to see what she'll do. Board is doing(crosses fingers) 233 fsb in dual with these dimms at 2.9v(don't know if it needs it or not) and 1.7vdd
only had a 100k pot so couldn't do the vdd mod yet.
Man if this board is stable 233 now at 1.7 I got a shot at 250mhz dual after vdd mod. Still haven't maxed board, but again this is all prelim. I have to say the peeps at hardcorecooling.com were very accomodating and I get them high marks for theri customer service. If this ram works out it's a STEAL, in the very least I trust them to honor thier sales after the fact.
thanks

nm back to errors :(

Do u have some more info? I'm in the market for new ram but i don't really have a lot of money and i don't want to be a guinea pig

[JNav89GT]

I'm gonna have to give this stuff major hands down. Maybe intel guys can use it but it won't run even single channel in an NF2 at 200+ fsb and loose timings. didn't try lower as what is the point, it's pc3700 memory and it should do it.
well at least they are friendly and had good CS so far

[isp]

Sorry to hear that :(

[JNav89GT]

yeah and i have some cheap kinstong PC3200 c2.5 valueram that will do 220-225 at cas2.5 3:6:3 timings so it's not the board erroring. Now maybe in windows in 3d it does but not in memtest. I think a vdd will clear the 3d stuff up and I will have a board that will top out about 225-235

I am confused. 1st you say it won't reach 200 fsb, then you say it does 233 (above) and then you say

Which is it? It reached 233, so how can you say it isn't any good?

[GVCryan]

I think he says its spitting errors at that speed.

[Nohto]

I know that my Kingston runs better (less errors faster FSB) if I use somewhat optimal timings. 5-2-2-2. If I try cas 2.5 I get all kinds of errors and if I try over 2.8v it also gets more errors. Also the nf7 2.0 has compatability problems with several manufacturers of ram. Corsair, Kingston 2 that I have heard of. You should try it on a different board.

[JNav89GT]

yeah I tried it on epox too and both the 1.2 and 2.0 versions of the abit.
it just generates errors at any fsb I set it at and any timings. sometimes I can get through looped memtest for hours, then I reboot and bam it spits errors on 1st pass. I have many times thought I figured out right combo of timing and voltage etc... only to be fooled. I dunno what to think now. I hosed the 2.0 board now and have to send it back.
