Hey all, I've done some searching and can not find a straight answer to what the max voltage it for my Mushkin Redline 2gb XP4000 kit is. I have heard any were from 3.0v to 3.5v, even one that said 3.9v is fine. Here is a link to my ram, <a href="http://www.mushkin.com/doc/products/memory_detail.asp?id=273" target="_blank">http://www.mushkin.com/doc/products/...ail.asp?id=273</a> and this is a link to what I have cooling them, <a href="http://www.evercool.com.tw/products/neon_crab.htm" target="_blank">http://www.evercool.com.tw/products/neon_crab.htm</a> I am trying to get them to 300mhz. Any ideas on max voltages. Thanks.<br />
<br />
PS: If you think the cooler as not good enough, I have a 120mm fan I can put on em.

I believe those have Infineon CE-6 IC chips so that kind of voltage will only reduce your performance. They should run best 2.6 to 2.7 volts and anything more then 2.8 to 2.9 would be unecessary in my opinion. The only memory that really needs that kind of juice to perform is Winbond BH-5 or CH-5, and some Micron can handle around 3.0 or a little more.

Only RAM that I see that actually improves from more than 3v is BH-5 & CH-5, and extremely budget RAM. (Read: "Value")

XP4000 redline should use winbond UTT CH-5 chips. They perform just like BH-5. Ive seen them up to 3.9v with good cooling. They should be able to do 260mhz @ 2-2-2-5 with 3.2-3.4v. Unless they are the later modols and use the CE-6 then no more than 3v needed

Ok so around 2.9 to 3.0 is about the most? At 2.92 they run 270 @ 3.3.2.6 perfectly stable. Is that about the best I can hope from them? I'd really like to get 285-300 from them.

...Er, you have CH-5 chips. Like TWS and I said, they like volts. Give 'em volts. Big volts. <img src="/images/smilies/wink.gif" border="0" alt="" title="Wink" class="inlineimg" />

With great timings like that at 270MHz you will have better performance than loosening your timings and running at 280MHz I bet. The best way to tell is to run your own benchmarks. You probably don't want to give them too much more voltage though.

It states in one of the reveiws on the page that they are Infineon chips.<br><br>
"...it was always at the better end of expected C die performance. Mushkin managed DDR436 at CAS2, where some other Infineon chip memory requires CAS2.5. Even at the very top, the Redline ran with complete stability at 3-3-2 timings and never required more than 2.8V for best performance. The highest overclock with Mushkin Redline was an outstanding DDR586 - the highest overclock of any Infineon based 2GB kit in this review."<br><br>

Oh man, you guys are gonna fry his sticks <img alt="" class="inlineimg" src="/images/smilies/eek.gif" style="border:0px solid;" title="EEK!"> . Those are <b>1GB</b> sticks, meaning they can't possibly be BH-5 or CH-5. Those are Infineon IC's, guaranteed. You run your voltage over 3.0 volts on those sticks and say goodbye to your RAM. 1GB sticks are too dense for BH-5 and CH-5 chips. It should be a given when you look at the stock timings: 3-3-2-8. BH-5 and CH-5 would have 2-2-2.

Thanks everyone, I guess 3.0v is about the max for these then. That's ok I'm happy with the overclock on them and how stable the system is. Even if I do fry them, I can just swap them with new, unless I melt them or something, lol.
