oh I edited my post sneeky with a screenshot my bad.

DAVE what kit number are your redlines?? mine is kit number 996805 there was another kit same timings and spd diff number that oc'ed much better

 

[erixx]

your board will set the memory at 1600 with the XMP setting.

1600 yes, sure! but not all small timings....

It's 996970. Crazy kit, I must say. I cannot max them out yet...8-11-8 isn't exactly "loose" timings, per se...would love to be able to max them @ 9-12-9, but my cpu seems incapable. It took alot to get that 2400mhz, as far as I am concerned...wasn't SuperPi32m stable, altohugh 3D seems easy...gotta play with them some more. I was kinda on a time budget to get those results done.

MatalRacer, you got about the same Memory Read speed and Latency as me @1600. If that is good for me or bad for you is another issue

I was just thinking the same thing:

After some tweaking...they are stable enough to run WCG. Not sure beyond that.

@sneeky my post is fixed to match yours

mastrdrver |1600 | 6 GB G.Skill Pi (blue) 1600 | 7-7-7-20 | 1.60V | 1.275Vtt | i7 920

I'll get a picture or two with the C7 Doms I have now since I can scale them past ~1700 where as the G.Skills would refuse to. Apparently I've got a 920 like Paulieg that doesn't need a lot of vvt to scale higher uncore speeds. I just have to keep the ram to uncore ratio 1:2 and it doesn't give me problems.

I'm trying to push my Geil sticks, but I have some questions. I'm wondering for those of you who are pushing vdram and VTT/QPI well beyond specs, such as 1.70v/1.4v, have you been running these settings 24/7, and if so, how long? Any dead sticks with this kind of juice?

 

[Wrigleyvillain]

As far as I know (and I'm not exactly an expert relatively-speaking) 1.7+ VDIMM can be dangerous over time but moreso to some chips than others, such as some older revisions of high end Elpida Hypers. PSC's etc are more resistant I gather (up to 1.9v apparently) as are the newer Hypers such as the MGH-E in the 2000+ low latency Super Talent sticks such as mine.

Also I don't think VTT can harm the DIMMs themselves; it feeds the CPU's uncore i.e. the IMC in this context.

i only do that when benching and use 1.6/1.35 for 24/7

 

[cadaveca]

Nope.

Now, My Dominator GT's died just running stock speeds and voltages. And seemingly Corsair wants to replace with a lower-grade model...contrary to the law...so if they do, I'll be sure to be fighting to have all Corsair products removed from the Canadian market, 100%. I got the time and money to fight for consumers...I don't think Corsair is ready for the fury I'm about to unleash on them, for trying to replace my 8-8-8 sticks with 8-9-8 sticks, and telling me that the little connector on the side makes up for the lack of performance...I don't think they are well versed in Canadian law. I bought 8-8-8, they need to replace with 8-8-8 or better.

Rant aside, that leads into something i have noticed over time.

Early 1.65v sticks requested 1.15v QPI/VTT in SPD, but now many are set to 1.35v in SPD.

Also, many boards just simply set 1.35v, even if the SPD dictates 1.15v.

Peet's been running well over 1.4v for quite some time now, as have others.

My rig currently requires no overclock to perform well in the things I am doing as of late, so I'm running stock cpu, and mem is stock, @ 1600mhz. The SPD of these mushkins is 1.35v QPI/VTT.

That kit that Peet is selling is 1.35v QPI/VTT in SPD. I am very curious to see what my replacements say in SPD.

Add 10% to 1.35v, and you get 1.48v. I feel, personally, taht this range is "safe", but there will, of course, be cpus that cannot take the punishment, and degrade over time.

Also, seemingly the HT chips need more QPI/VTT than thier quad-native bretheren.

In the end, when it comes to clocking, if more volts increases the clocks, I'm gonna give it volts until it either breaks, or no more gains can be had.

I have been benching my ram all evening, and ran into funny results, sometimes the Read and Latency went bad when I expected them to improve, as low as 14.000 read and 45 latency. Now I finally got a good result that I will keep.
The hard part is that CPU and RAM are so related, and set both in their own sweet setting without undoing something else... Well, thanks to all of you for encouraging me again to do this

 

[sneekypeet]

Sorry guys I will get on the update soon, just dont feel like working much today

@ Paul....with my P55 if I run 1600mhz or above my VTT needs to be pushed to 1.4V, if I go to 2K speeds I need 1.44VTT minimum.

I have run my tridents since I got them from Cold Storm at 1.74V and 1.48VTT since I got them to 2400. Same can be said for my Patriots, but the ram voltage is dropped, they do 2400 stock, but still required 1.48VTT to function.

I'm not sure how the X58 holds over the long term, but my testing and abuse is 6 months strong and still counting

Plus, that first kit was being abused for 8m before you got it..

 

[sneekypeet]

quite right, so essentially a full year plus of real abuse. They are still my go to ram for high memory speed benching, even over the Patriot 2400s, the Tridents just go faster

 

[Cold Storm]

Just benched my PiS... Gigabyte loves it at 6-9-8-21. Just finished an hour of Fear 2.. lol

 

[erixx]

my nice results : Ram Tweakers Version DDR3
are not stable playing BC2 (again...), locks the computer ... Damn, I am clueless, gotta study VTT...

 

[Cold Storm]

why are you using a 18x multi when that chip has a 20x multi?

 

[erixx]

'Cos the original FSB is 133, the XMP profile is 160 and I am running it at 200 Mhz...
Thats why I lowered the multi....

 

[Cold Storm]

Running what at 200mhz? the CPU is at 210..

what's your vtt set at?

 

[erixx]

Sorry Cold Storm, I mean "around 200", as I have been testing 195, 200, 205, 210...
VTT, no sign of that in Aida64.
I have PLL at 1.80 and IMC at 1.27...

thank you!
