Sorry if this is a little OT...
I've been tesiting my G.Skill kit (RipJawX 2133 CL9) with a bootable MemTest CD.
My question is, can you use this method to test the IMC of an FX chip as well?
In other words, can I use MemTest to check IMC stablility too, or am I wasting my time...
Thanks,
Dave
I'm not sure if you were given your answer but I had problems with overclock of memory on Llano too. My(The) solution is to loosen a bit the secondary timings. I presume they are loaded automatically without checking the SPD and sometimes interfere with the memory's timings. I was stuck on 1950 CL10 beforehand now I can boot up to 2300 CL9 1T and really still haven't found the maximum.Quote:

Memtest DOS based would pass much better than the last two I have mentioned. Better to test @cold too!

After some testing it looks like you can get it roughed in, but it won't neseccarily be Prime Blend (max mem) stable.
Thanks Folks! :up:
FWIW, I have this kit (G.Skill 2x4Gb 2133 CL9)

The best I could get 3 pass MemTest stable was ~2160 @ 9-11-10-22-32 (300ns) 1.6625v.
To be fair, I get bored with mem testing but his might give someone an idea of what this kit can do stable...
If anyone has this kit and can offer some tips I'll be willing to test. ;)

You might gain more speed with tRAS @ something higher than 22, tRAS is usually about CL+tRCD+tRP anyway.
You can't tighten to 2133 9-11-9-22, can you?
Beep: Thanks for the tips! Ram clocking was never my forte' and an 8Gb kit doesn't help that... :(
I didn't realize TRFC had that big of an effect on performance. I've done some more testing and the best I can get STABLE @ 160ns is ~2050.
I was just pushing for max frequency to see what I could get MemTest stable.
9-11-9 is a no go @ anything over 2000mhz (didn't test lower freq than that yet)...
As far as tRAS and tRC goes, I started out with clocks @ 9-11-10-30-39, and once I found stability, I lowered the last 2 until things started failing.
Thats how I wound up with 9-11-10-22-32. :p:
I hate to sound like a noob, but I've done all of my testing (so far) at 1T....
Since it's an 8Gb kit would switching to 2T help or seriously hurt overall performance?
It sucks, because I can bench this kit ~2300 9-11-10-24-36, but I had random lockups/failures for 24/7 use. Narrowed it down, definetly Mem problems. :rolleyes:
I'm really surprised the kit won't do 2133+ @ 160ns...Quote:

I haven't been able to use my rig for two weeks now, I tore apart the WC the weekend before last to find nasty stuff in my block, left tubing out overnight...was a bad idea. Have yet to order new tubing and the laptop I'm using has a broken cooling fan. :rolleyes:
You can test though, run your muskins up to 2000 or whatever CL9 and test different tRFC. At 2000 your PSC kit should do 90ns but you might need to lax to 110. 90ns was easy with Hyper up to 2133 on both Thuban (unstable) and FX to about 2100. 2170 (max) needed 110ns.
I haven't tested Command Rate with FX, 1T works on my Hypers up to 2400 and PSC up to 2550, unfortunately it never got cold enough here to test past that and I have no time to set up for a DICE run, currently school is more important. Besides, my current 8150 has a much weaker IMC than the first. I think the first could have pushed to 3K+ on DICE or colder, this one won't boot at all on the 2400 divider or past 2300 on 2133 divider with PSC I'd shown benching 2500 7-11-7-27 on the first CPU.
What happened ,why you change the CPU ?
Gonna order a pair of "some" mem in a few hours i hope (been waiting a freaking week for paypal, err, more like a darned month actually).
I'll tell you guys what I ordered afterwards lol, last time I posted what I was planning on getting before i ordered it and it was gone before I got the chance to place my order.
Can't wait, excited.
I'm afraid that 8gigs isn't gonna be enough for me though, I know i can get away by using the 2 gigs that I got an 4 gig swap but I can imagine that amount of ram won't hold up forever without a swap.
I almost wanna order 2 pairs but I'm afraid that my clocks and timings will suffer horribly.
Let alone the hassle I'll have getting each of the 4 sticks to work in these flimsy ram slots that work 50% of the time.
Went form dfi 790fx with extermely piss poor ram slots to this asus that again has some pretty crappy slots.
Screw it I'll ask, what do you guys think?, 2x or 4x sticks of some good ram?
Supposedly these days they match up quite well, cmd1 with all 4 sticks, tight timings with sticks sold as quad chan, etc.
I'll buy 2 pairs, but only if the timings don't suffer much.
It's either psc or hynix, not sure of the actual chip on the sticks I'm looking at, either is probably just fine.
Can't believe I'm actually saying that, hynix lmao, that's something I'de just throw in the garbage but not these days...
I got two 2x4gb kits from Kingston (KHX1600C9D3T1K2/8GX), they where dirt cheap and did 7-9-7 1t 110ns (90ns = no post) ~1700mhz with 16gb installed before my fx-8120 broke down. Havent tried to OC them with other CPU's yet, but doubt they'll do much better. I would stay away from them if you want some nice OC, but for a daily cruiser rig they are pretty decent value I guess, with good warranty. Runs very cool with close to no air flow.Quote:

Yeah I know.
I could get 4x4gigs and end up not being able to clock them like I wish.
Another thing is it's double the cost for another pair, when I could use that money on say an ssd or something completely different.
So I'm just gonna buy 1 pair, save my money, heck I could afford 2 pairs of samsung np, ohwell.
It's 5:44am and my money is still not in paypal errr lol, I hate waiting I just wanna order my pair of mem :).
My 1t choice was the geil eva corsa 2400, thing is there's 3 diff bins of it.
9t, 10t and 11t.
9t is only sold in the quad chan kits and I haven't been able to find it at all.
10t and 11t is sold on newegg and everywhere else for that matter.
But that's not what I'm getting anyways ;)
Gonna go check my paypal.
If my money isn't in there I'm going to bed, gotta be up in 5 hours :\.
Edit: darnit paypal..., sent my money to it on jan 27th, I hate waiting a week everytime I need to get a debit card or something.
ANnyone tried the new samsung low profile low voltage kits on P II?
Yeah. Look @ my signature.Quote:

I ordered a pair of the adata.

Seems like it could be the right set of chips on it whatever they may be, probably hynix.
And the pcb could be interesting too, might make all the diffrence.
It was $80, half that of the geil 2400, $10 less the the geil 2133.
I was turned off by geil's heatsinks.
My 2nd choice was the mushkin redline 996997:

I did have an issue placing my order, opera refused to finish loading some of the last pages of the order so I had to redo it all with firefox :(, that pissed me off but ohwells...
Edit:
Haha I knew it :).
As soon as I mention what mem I'm gonna get it goes out of stock funny that.
It's cool though I got my pair coming on the way :D.
Oh yeah, Um, I was thinking since the pair I ordered had a 8 layer pcb instead of a 6 layer one, and 2ounces of copper per stick, perhaps it won't be such a hassle getting them to post in my board.
Just a little thicker then avg and I think it'll work every time I insert the sticks.
I have an issue where on my dfi and my asus, I put a stick in and it doesn't post, gotta re-insert it a few times to get it in just right.
Hopefully that sort of prob is in the past with these new sticks I'm getting :), just a theory :).
I don't have the sticks yet though to know for sure, but it's one of the things I'm hoping for ;).
not bad at all, Crucial Ballistix Elite 2x 4GB 1866Mhz 9-9-9 1.5v (probably 30nm Micron)

Sold some parts to a friend who's rig died, including my spare 8Gb kit.
SO... I ordered a kit of Geil EvoTwo to replace them (just to have a spare set).
http://www.newegg.com/Product/Produc...82E16820144493
I'm not really expecting much from them, but I'll push them a little when they come in and
post some results.
Anyone tried that kit yet?
Not me but I read somewhere they are very good (seemingly to A-Data XPG V.2.0).Quote:

Nothing died, sold a board, 965 and my extra kit to a friend. :p:
Hope your right about them clocking well!
If I can can get decent clocks on them you'll know they're good 'cause I suck @ ram clocking... :yepp:
It is not so hard actually seeing that most stable clocks can be easily obtained with auto\SPD timings (and you can read them from Everest\Thaiphoon Burner). Tweaking is needed essentially for quite extreme OC (with command rate, trcd, trc, trfc as critical timings).

If I can get 2133 out of them on this config I'll go for it ;).
I'll do what I can anyways.
Main issue right now is my os, win2k3 x86 is to hard to install, no floppy for raid, but it should support all 8 gigs of ram.
Win7 x86 doesnt' support more then 3 gigs I think it was.
I have x64 as well.
I ordered an ssd, one of those sata3 500megs per sec ones with 8x,000 iops types of stuff.
I'll be using that as my os drive.
Won't be in an array so it should be possible for me to install win2k3 again, and if needed win7 x64.
Plan is to use it for quick managing of os partitions so I can figure out the kernal mode for win7 x86, gonna hack support for more ram, just need to get past that signing stuff.
Can't go testing the ram with less then half of it showing up ;).
Oh anyways.
Ram comes on monday supposedly, ssd not sure.
So I'll be using win7 x64 for a little while in the meantime.
Gotta do what I gotta do :\, wish I didn't have to hack x86 but it's something that needs doing :).
