How much voltage will TCCD take before it gets damaged?
I think after 3.6V it will be damaged. :)
Anyone have tried it? :confused: :p:
For tccd431 2.65/2.7V is the spot and for tccd440 it can go higher(prolly even at 3.0V up)
How to know if they are 440? :confused:
Using CPU-Z? :)
No, by looking at chips.
My TCCD 437 perform pretty good @ 3,2V
265 2335
300 3448
Just make sure to keep them cool if you start pumping some volts into them.
will heat spreaders do it? or do i need some sort of active cooling?
Take the heat spreaders off, they hurt alot more than they help. Give the memory a weak 120MM fan and you will be good to go.
how about keeping those heatspreaders and still put a 120mm on them? :)
anybody take a look at the chips on the PQI Turbo PC3200s?
The PQI Turbo PC3200 w/XBL 2-2-2-5 have TCCD, dunno whether they'r 431 or 440..
how about hte ocz 3200 plat.. anyone know which they are...
My Gskill with TCCD 440 max vddr is 3.15v. Anything above is unstable.
Pulled the HS off my corsair and they are 437 TCCD. would I benefit from a 3.3Vmem mod ?
I can manage 300 @ 2.5,4,4,8 2T 2.8v but lose 1T at 280ish regardless ov Volts or timings.
Also is the AGPvolt and Chipsetvolt tied on the Neo2 board ?
tccd is so finicky about volts. it seems specific speeds need specific voltage or else ram becomes unstable. I have later tccd that like voltage. My best results at 280mhz+ is 3.1-3.3v I have pumped 3.6 volts into it and the ram still works fine. This is week 40 and higher.
Correct, with 431 TCCD high voltages only works with CL2.0-3-3-5.Quote:

rite now im using Kingston KHX3200ULK2/512.. izzit 437 or 440?
Thanks, Im just dragging through the rather long threads about TCCD now to see If there is a connection between dates and volts. Must be a week that something changed but what is it...
The trouble with most ICs (including TCCD) is they have built-in current regulation units, called "stabilitron"s. I don't remember exactly how a stabilitron works, but it's a very simple device, like a diode. These things only work in a certain voltage range, lower - it won't let the current through, and higher - it just puts out extra heat (heat causes instability). Theoretically speaking, if TCCD did not have these stabilitrons, it would react to increases in voltage much like our beloved Winbond chips. There are rumors that there is another kind of TCCD, "mobile" TCCD (edit: that supposedly doesn't have the current regulation circuitry for one reason, or another). There are also rumors that Mushkin is putting the said "mobile" TCCD on their pc3200 lvlII V2 sticks. Ne1 wanna try it out? ;)

Good heatsinks only work because of the extreme amount of surface area they have, the heatspreaders don't even have 50% more surface area. A XP120 has around 100 times the surface area of a cpu.
Yeah. To make it worse, most companies use cheap double-sided tape, which is full of air pores. It's like putting a warm winter jacket on your ram.Quote:

i have some tccd thats marked 440 and right now i got 2 sticks of 256 running 290x10 in my DFI 250UT/3400 system 2.5-3-3-7 2.7v should i be using more voltage for this speed? i have tried the 3.10v trick with the 2cas at high htt and the memory seems to be fine at 3.10v. i just neve put it that high cause at 2.7v i can run 2 sticks at 290 so im happy righ there....
peace perc,
I've got some 431 gskill and it runs 240mhz on 2.7v and 2.5-3-3-11 timings, but i'm on nf2 board :( Can 431 do 2-3-3 with 2.9v? And does it like higher volts like 2.9v at higher speeds?
431 is low vlt loving stuff TBH.
You should be ok to 230 at 2.3.5.3 with 2.7v , try dropping your volts as some users have reported that volt hikes just decrease stability
Same here. (Gskill LE / TCCD 437)Quote:

Currently running P95 for 12 hours @ 240fsb - 2.0/2/3/11 - 2x512 - DC
Upping the Tras to 11 really helped. And since the nForce2 boards run better
at Tras 11 above 200fsb this was not a problem.
I've had these Mushkin's also. lets just say they wouldn't work well no matter what volts I put through them.Quote:
