View Full Version : Here it goes...more voltage to my ram!

I'm gonna try out 3.0v on my GeIL Ultra Platinum DDR 400. It's not doing well at 2.8v, because it's a Windbond CH-5, which takes a lot of voltage.

If I put a side panel fan directly on top of the ram, will that help?

If your feeling like taking a risk, Go for it :D

Will definatly need a fan next to it tho :p

Well because it needs 2.8v to be stable at DDR 400. It's Winbond UTT CH-5, and it can handle up to 3.5v....should I infrared? I'm putting the fan on the side panel right over the two sticks.

if it's ok for up to 3.5v, 3v should be absolutely fine. it's only 0.2v over stock :)

Bad comparison, but i run my ddr2 w/ a stock of 1.80v @ 2.1v often. Just saying that most memory is designed with quite a lot of overvoltage headroom.

It took me hours to adjust the 20 or so memory settings on my DFI...and I hope this helps. Check you PM, I need your help...

I used CH-5 memory on my lanparty B for hours at 3.3V with no issues. In my experience CH memory doesn't notice any improvement above 2.6V until you get to 3.1V. I heard they have built-in voltage regulators that somehow fail at 3.1.

Poinsonsnak, did you have an active fan on them? Did you get better results with higher voltage? Mine is failing memtest86+ at 210Mhz if I stay ay 2.8v

No fan, but in the antec sonata I think case cooling is pretty good.

I found that if anything my results were worse at 2.8V to 3.1V than 2.6V.

On my lanparty B I could do 250MHz 2.5-4-4-11 with 2 512MB sticks of Corsair RAM with CH-5 at 3.3V.

edit: also it's been a while but if I recally correctly this RAM performed better after being "burned in", like running 2.5-3-3-11 (the 11 is an nF2 quirk you can probably do 8 or something) at only 220MHz 3.3V for hours on end on Memtest test#5 to get them as hot as possible and then they would overclock better. If you can track down "uwackme" on DFI-Street he can explain it a lot better than me.

Guys, a hardware question I need info. on:

Is it THAT easy to "burn out" your memory thru overvolting?

(And, is the memory controller portions of a system in danger as well??)

* Thanks for the info.!

It's not very easy, at least not with the kind of voltages you're talking about here... a friend of mine fried his oldschool pair of bh5 running them on 4 volts.. several months. The 'default' voltage for old bh5 should be around 3.6. CH5 do not like volts that big however, 3.3 should be enough to see their potential, or a little more temporarily (at least utt ch5, don't know about the old ones).

i have my patriot ddr2 at 2.3 volts and it seems fine.that is what they say it will take without voiding the warranty tho'.

"overvolting" is a term that should be used loosely. best thing to do is to dig up the datasheet for the IC in question your RAM uses and look at its tolerence, and not exceed that. as for the mem controller, in your case its on the cpu, theres no effective way for telling when the mem controller is in "danger" as the instant you go past 200MHz its all unknown territory. As a rule of thumb however operating beyond 270-280MHz for 24\7 usage probably isnt a very smart idea.

Ketxx, I still can't overclock well at 3.1v, should I try 3.2 or 3.3v...since most people with CH-5(UTT or not) are getting better results at these voltages...should I try it? I have an 80mm side panel fan directly over my memory modules. You're the memory expert here so...thanks.

are the ICs actual CH5? can you post the info on the ICs? and a nobrainer i know, but u did remember to put the modules in the yellow slots on your dfi right? :p

Why yellow? Isn't it supposed to be in the orange slots? Or else that's what I was told...

Ketxxx

erm..hell no! the orange slots are for memory with ICs such as TCCD\TCC5 etc where the yellow slots are for BH5\UTT\CH5 etc. you might want to make sure your running the latest bios for the board as well to take advantage of everything possible in the way of bug fixes etc.

I'm running the lates "official" DFI BIOS, not modded ones specifically for TCCD or Windbond BH-5/CH-5/UTT chips from DFI Street. Should I move it to the yellow slots? Is that going to make my overclock better (if I do have CH-5)? Should I flash the BIOS to a modded DFI-Street BIOS?

Ketxxx

flashing the bios is up to you, moving the CH sticks to the yellow slots is a must ;)

Alright...I have to get my homework done, so it'll be a while(2nd day of school and 4 pages of HomeWork!). I'll either post up back here or send you a PM.

Btw, should I clear the CMOS, or go back to default settings before I go switch to yellow?

Ketxxx

you can just switch slots. but for completeness you can clear cmos if you want.

Ok, I've heard some people getting problems switching without clearing CMOS on DFI Street. I'll send you a PM or post back when I do it (hopefully soon)
