CPU/Mobo Should I pump 3.3v to the DDR?

Well as usual I encountered some problems with my latest build: first of all I am stuck at 2.5Ghz , but more on that later, somehow I believe the ram is holding me back(should have bought the PC4000 but ahh well...),I am having a hard time stabilizing it at 1T, 208 Mhz(cpu is at 10x250, 166 mem divider, vcore@1.52v) even at a relaxed 2.5-4-3-9.The stability seems to increase with more VDIMM(won't boot at 2.7V but passes 3DMark at 2.9v), now the tforce board has a setting for 3.3v dimm, should I use it or will it probably lead to an immediate burn-out of the DDR?

I am kinda disappointed with the board too as so far attempts to get it over 250 HTT have failed, but from what I have read the max HTT depends on the CPU and ram as well, irrespective of dividers(surprising), so for now my aim is to stabilize the thing at 2.5ghz, which I think I can live with b4 switching to conroe next year.;)

I am hoping that 3.3v will lead to a big increase in max ram speed as well.Inputs from people who have crossed the 3.3v barrier most welcome.
 
You will have to first see if its the processor thats holding you back.

Your processor may well have limits at 2.5ghz.

set memory divider to 133, cpu multiplier to something low as 9 or 8, HTT multiplier to 3X and push the FSB and see if the board now goes more.

IF it does then its the processor thats hitting wall.

If you push 3.3v in anything other than winbond, you will mostly kill it instantaneously.

The board should definitely do more. i got 6100-M9 flashed to 6100-939 upto 300HTT.
 
^^yeah now I think I should have got the M9 and used that , it was going for a measly $37 for an open box one, paid $75 incl shipping for a 'true tforce',lol.To add to more to the insult, there is a $10 rebate on it (tforce 6100)now!

----------

Plus I think the board is limited as well or it has something to do with the memory which has SPD only for 200Mhz.Won't go over 250 even with the multiplier set to 8 and ram to 133.Guess I'll RMA both of 'em next month, the board and the ram.For now at 2.5Ghz, ram at 2.5-3-3-6,2T, just my luck!:@ :@
 
Okay so 3.3V is deadly for anything other than winbond?I read a review of ADATA DDR500 which was stable at 3.6v using DDR booster, seems to gimme hope...
 
Winbond is cheap maker. Their UTT are famous for high voltage low latency operation.

Multiple ram makers use these chips but you need to make sure your ram uses it before applying such high voltage to the same.

what ram do you have? have a look at techpowerup memory database and see if you can find the chips on your ram.
 
Well thats the problem, I am yet to find out what chips they use.Since they were from Gskill and did 2.5-3-3-6 and on some reviews got up to 230-235mhz, I bought them, talk of lowered expectations!

One odd thing though, when I downclocked my CPU to 5X250=1.25Ghz with mem at 2.5-3-3-6-1T it was stable!Perhaps the CPU mem controller can't handle 1T at high frequencies,already at 1.56V and don't want to push it further on air, even though the AVC HS that HP used is quite big with a nice fan and I applied artic silver ceramique as well.
 
Tried it didn't help one bit.Will prolly RMA the RAM soon.Seems the NS series has chips that fail to meet the GX and HX requirements and can be Samsung,Infineon or even Hynix.So its a lucky draw as to which u get.The chips are relabelled so u can't really find out but I'm guessing I ended up with either D5 or BF-5/6.But that really makes me wonder as to how accurate G.Skills claim of 'six hours rigorous testing of each module' is?I didn't expect wonders from this just about 210-220 at 1T and 2.7V-2.8V which most good value ram can manage.

Will be testing at 2.7V for what its worth coz apparently many 'NS' parts work best at 2.68V.
 
Obtained the RMA number from newegg, now I am facing a new problem, the 1800XT gives me 'lost focus' and/or VPU recover error.I think I should RMA that too, just in case.Hell...I think the best course right now would be to RMA the card and ram, send the board for a refund and get a new DFI ultra or something along with a ATX case.Its Sunday today so will have to make up my mind by tomorrow, sure will have to spend about $50 on all this but I think it would be worth it.Must say the Tforce is a big dud.

Update:Will be sending both the card and the ram for RMA tomorrow.Haven't decided on the mobo yet.
 
just disable the stupid VPU recover. ITs really problematic at times.

And honestly do a clean format :P

Having these errors can be software related most of the times.
 
Well thats why I didn't RMA the board for refund yet.However when I disabled VPU recover the screen simply froze, may be its all coz of the crappy ram but hey better to get 'em both replaced while I am at it right?
I did re-install windows but due to the enormous amount of data in my hdd, a clean format is not an option right now,will need massive backup b4 that.(yes I have things other than pr0n on my HDD!lol)
Will ship it out tomorrow and hopefully should have the items by next week.
If things do not improve then I send the mobo for a refund , dump the case and get a new DFI and ATX case.
Among other things,I tried keeping a fan to blow over the GPU vrms as the mobo SB and GPU vrms almost touched so I thought might be a heat issue but that didn't help matters either.People do run the X1800/1900s on the Tforce given that it is so popular so that was a non-issue anyway.
Hopefully the RAM won't be a dud this time round as many ppl have reached 220-240 at stock timings and voltage with these.
 
Sent it out for RMA today won't be back till late next week at the earliest:works best as I have a midterm this week and work in the weekend.

Praying that this time I end up with UCCC or TCCD.
 
^ Why dint you get the GB HZ series? The NS series arent that good at overclocking.

BTW, TCCD or Winbond stuff doesnt exist in 2GB kits - i'm guessing because the chips werent designed in higher memory density versions.
 
^^ Was trying to be a miser-may be went too far at that!Saving 15 bucks is gonna cost me more if the sticks that arrive this time are bad too.Basically my thinking was 400-440 at 2.5-3-3-6,1T is good enough and I could use dividers to overclock as A64 shows little benefit from high mem speeds anyway.Ofcourse I didn't bargain for a bad pair of sticks.The almost all +ve rating also influenced my decision somewhat.Too bad newegg ain't walmart or we wouldn't even be having this discussion.Use,break and return to walmart in three months-lol.

The closest you can get to BH-5 / CH-5 in 2GB DDR kits is Infineon CE-5 which are mostly found on the high-end GSkill kits.

@ Sid - TCCD/5, CH/BH-5 are 512MB only ;)
 
My PC came with 2 X512MB CE-5 originally so I know how good they are.But some of these 2GBNS parts are good too-reaching 235-240 on stock voltage and timings.My bad luck that the one I got wouldn't work even at 200 mhz at 1T.And this Tforce sucker won't boot above 251mhz(I am thinking this is due to the ram as some boards just don't get along with bad ram).On my bro's PC the cheapo ECS board did 289-290 with ease and using the 133 divider I was able to reach nearly 200mhz on the ram too.This with 512MB D43 and 2X512MB infineon CE-5 for a total of 1.5gb.
 
Well if things don't work out with new ram, will call up GSKill , ask them if they can resolve the situation or else give them a piece of my mind and order a pair of those delicious OCZ titaniums from the egg.
