Max safe D9GMH 24/7 volts?

[WeStSiDePLaYa]

What are your opinions. Ram in sig.

[EnJoY]

2.2v-2.3v

[WeStSiDePLaYa]

2.2v-2.3v

Really that is it?

The stock volts for my ram is 2.35 +/- 5%

[TSFroggy]

EnJoY refers to "common" Micron D9. Those ICs in the FlexX in your sig have been picked and tested and are (hopefully) found to sustain voltages up to 2.4v. That's the theory at least. Why would they warranty them that way if they didn't for most? :P

[Noob-ftw]

Well, from my experiences, I wouldn't go past 2.2V for DDR2. (24/7)

[jimmsch]

I had some Firestix that were RMA'd every three months from running UNDER clocked at the recommended voltage of 2.15v. DDR2-1000 running at DDR2-994 using stock timings and 2.15v lasted exactly three months for me...twice. People blame my motherboard (P5W H Dlx), but who knows.

[aznsniper911]

Well if it's rated for 2.35 then it should be at 2.35V for stock! I been running my Crucial Ballistix DDR2-800 with 2.4V with no issues!

[EnJoY]

Good luck with that.

Team even has some D9's with warranty up to 2,45V
but for the price they charge they prolly allready factor in 2 or 3 rma's.

i've pushed 2,55V through d9's for benching (with hr07 and fan on them) and they are still alive, but i woudnt run more than 2,3V for 24/7.

2.2V max and that must be DMM (not bios set). Listen to what Crucial says and think about who makes Micron chips

[AngryArtichoke]

2.2V. But if you really think you'll actually see a difference, go as high as the warranty will cover.

[WeStSiDePLaYa]

2.2V. But if you really think you'll actually see a difference, go as high as the warranty will cover.

It's the difference between 288 5-4-4 and 288 5-5-5.

So since it has warranty higher, I'm sure it can handle it. Some insight from OCZ would be nice though.

No... 2.35v is the rated voltage for PC2-9200 (1200 MHz) operation at 5-5-5-15 timings. EVP is 2.35v... no +/- 5%.
Read the fine print under EVP right hand column: http://www.ocztechnology.com/product...lexxlc_edition

24/7 use on 2.35V is covered by warranty.

Ok thanks, guess I'll stick to 2.35v for warranty.

DMM reading is what i recommend too, some gigabyte boards overvolt vdimm by more than 0.1v!

[KTE]

Rated specs whatever they are, if at or above 2.2V at ambient >22C, then make sure some fan air is blowing across them. Even 2.1-2.2V can and has killed D9s, they run very hot at stock.

[zsamz_]

my mushkins xp2-8500 are rated 2.35v
first 2 kits i was @ 2.26v 24/7 both kits lasted 2 months had 2 fans on em they never got warm to the touch
now i keep em @ 2.22v 4-4-4-12 1000mhz
my ballistix 8500 can do that with 2.1v and 1200+ with 2.13v

Asus maximus (ddr2) also overvolts by 0.08-0.1V! Same with maximus extreme (ddr3) - overvolts by ~0.06-0.08V. No idea why they do this

[The0men]

Had OCZ SLI 8500 running 2.4+ 24/7 for a year, and benched it up to 2.7v and never had a problem, though it didn't scale aswell up there in the volt's as it did from 2.0-2.5v.

I actually thought I killed those sticks during a bench at 2.6v, but nope, theyre still hanging on, just a RAID issue (used some different files from the driver set)

So even though I wouldn't recommend going over the EVP, it is there for a reason, I would expect safe operation at the EVP (2.35v) 24/7. Seeing how they're flex (im assuming you have them with liquid) then keeping them cool shouldnt be an issue.

LOL I see some people worrying about .1v overvolting, try 0.7 on my P5N32E-SLI.

I was investigating OCZ website and found out some interesting facts...

All OCZ Reaper (D9) and Flex (D9) stuff are have warranty up to 2.35v. And to do stock they need 2.1 - 2.3. But there are OCZ Alpha Titanium VX PC8000 which have EVP up to 2.4v +/-5% and it's stock is 2.35v

**OCZ EVP (Extended Voltage Protection) is a feature that allows performance enthusiasts to use a VDIMM of 2.4V ± 5% without invalidating their OCZ Lifetime Warranty.

Is that mistake or true facts? If it's true, why OCZ gives for some series limits of voltage as basically they use the same D9 GMH and identical 8-layer PCB?

Did I hear you right, 0.7V? That's not normally possible. Minimum ddr2 voltage on your mb is 2.5V? lol

[Xtreme Addict]

Hmm P5N32E-SLI allows up to 3.425v if I remember correctly (maybe it is 3.450v) but in fact this motherboard is ram killer... and I am honest in this term now...

[KTE]

Looks like he meant his MB overvolts by +0.7V

MSI RD790 doesn't overvolt, usually undervolts by 0.028V, DFI RD790 overvolted by 0.035 and the Sapphire RD790 overvolted by 0.0133-0.0136. In either case, you need to know your DMM readings.

[The0men]

You are right, I stuffed up, .07, which doesn't seem so bad after all.

They are probably killers because people don't realise they're overvolting.

I didn't know other boards also had this occurance. And yes they have some insanly high DDR voltage
