Hmm 1.8v though and its probably overvolting the sticks a bit.
Impressive, but not completely impressive. My current FX-8150 IMC won't do 2400, but I'm sure I can push ~2200 6-10-6 easy.
Not exactly world records but really impressive konalos :D

I can run my g.skill pi 2000c6 up to 1079 mhz 6-9-6-22 1t @ 1,69v with thuban x6 cpu.
After 1079mhz the imc gets out and i won't hit a higher score. not even with 7-10-7.

You are totally wrong. SuperPi is not a good test for memorty stability. It test them just barely. At least you should try Memtest for Windows (several istances). SuperPi is a synthetic test and can be done also with unstable overclocks.

for 24/7h use just lower the clocks a bit like ~30mhz +/- and prime blend will run in the most times. you know what i mean..
If it can run 32M it's pretty stable i can assure you!
I have the exact same ram.. patriot gamer 2 1600? I tried (also on Llano) everything, and no voltage would get anything above 1600 stable. I also tried 1866 CL11-11-11-32 or something, and still got that ugly graphics corruption.Quote:

That's quite good with the Samsungs..and they are only $60 and low profile. I wasn't sure if they would play well with AMD. How do they do at higher speeds (2200mhz?)
He can't do above 2000 with them on Phenom II X6.
Any idea how they do on Llano?
2133 10-10-10 shouldn't be too hard.Quote:

Like this Prime95 fails after few seconds!!!
Yeah.. I heard its hard to stabilize the Samsung ram even at 1866. I am thinking of trying some g.skill ram on my llano still looking for something good. Do you know what PSB means? I'm guessing its some chip mfr. I read they work well with Amd. Or hynix bfr.
Is there a guide for which ram sticks have which chips?
The bad thing about Samsung is that they doesn't seem to benefit anything putting voltage above 1,5V (I tried also 1,8V lol). Zero gains. Very good for ~1800Mhz 8-8/9-8/9 btw (with only about 1,45V/1,5V).

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!

Thanks Folks! :up:
FWIW, I have this kit (G.Skill 2x4Gb 2133 CL9)
http://www.newegg.com/Product/Produc...82E16820231476
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. ;)
Hint:Quote:

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:

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.

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 ;).

I'm not really expecting much from them, but I'll push them a little when they come in and

Not me but I read somewhere they are very good (seemingly to A-Data XPG V.2.0).Quote:

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).

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 :).

Don't remember if I've tested 5-6-5, but here's one screen with 5-5-5. I don't even remember what was the purpose, but I believe it was for a competition, that's why the cpu is < 4.5GHz.
Probably can go higher with that timings.

The mem was freaking me out for a min there, wouldn't post 2000mhz.
Ended up that the bios wasn't setting it's auto timings correctly.
The bios apparently was only meant for timings up to 9-9-9, not anything above.
Setting to 9-11-9-28 cmd2 fixed the issue.
1st run, got to test 4 in s&m's memtest, midway and it errored out.
2nd run, I changed memclk drive strength from 1.5x to 1.25x, ran it and took off to get food and such.
Got back and it passed.
Ram is running at 1.65v, ref voltages are stock.
The bench above with aida, extremely low bandwith, that's not how it actually is.
It's normally 11k, 10k and 15k, for some reason the bench above was giving way wacked out results when having s&m in the bg like that, ohwell.
It's only to show the specs of the mem and such.
Had s&m setup with the config shown and with a video running in the bg, gotta have something to look at while I'm waiting 20mins for a test...
Gonna get my drink on and keep testing it ;).
Oh, I do want to mention this ram fit nice and snug in my mem slots.
No lossy goosy here at all, nice and tight with no wobble what so ever :D.
Also posted right away, didn't have to re-insert the sticks.
I'm glad I pick the set I did, normally getting this board to post at all when putting mem in is a real pain for me.
Edit:
Can't continue, to blown out.
Will continue tomorrow, probably shouldn't of drank a 5th to myself.
I just can't sit around and wait 30mins per test right now, I did figure out a few things about the drive strengths, but it's not final.
Going to bed in a min, gonna try again later.
Attachment 124031
Ok, what I did next was get cmd1 stable.
In order to do that I had to change the data and control ref voltages from 0.500x to 0.510x, both of them had to be that amount before cmd1 was stable.
Perhaps this would be easier if my nb/ht speeds weren't 3ghz, ohwell.
Ram voltage and so on are still the same as before.
Attachment 124032
Didn't change anything to get this.
Cas8 and tRC of 12.
What's strange, tRC should have no issues doing 11t.
Something is wrong, either the cpu is to blame or the bios.
I never noticed the issue before, either it has something to do with the ram size, or the ram chips themselves.
Very strange, ohwell, not a biggy because amd doesn't support much lower on there mem controller anyways, I'de be freaking out right now if it allowed 0t and wasn't stable.
Tried setting tRCD and tRP lower but it's unstable.
Either my voltages or my drive strengths aren't at there pinnacle yet.
Sorry for the triple post.
Mem bandwith is pretty lame, but then again my cpu clock isn't up there.
I'm expecting 14k, 10k and 17k in terms of aida64 bandwith.
This is the last of my testing for a few hours, gonna go over a buddies for a little while :).
Edit:
Final timings:
8-11-9-25-6-12-12-4, 6-2-4-3-3-160ns-7.8ms-1t, 2000mhz
Hey Dave, be really careful. I wouldn't put much more than ~1.85 through that IMC. 2v+ was killing Thuban and late Deneb according to chew* on 45nm. The older Deneb chips do 2.4 easy but its the ram that dies then XDQuote:

I don't mind if the max is say 255mhz bus speed, as long as I can inch it up a little bit higher then what it is.
I could not figure out how to get the main timings any lower either.
Max volts I pushed into the mem were 1.7125v, I was afraid to go higher, didn't seem to help anything above 1.65v, I don't even know if I need 1.65v for 2ghz (didn't try lower yet).
I'de like to get tRCD down to 10t, and tRP down to 8t or 7t.
Anyone know what drive strengths these mem prefer?, that could be a major help.
The best you will get out of Hynix (Are they Hynix?) is ~9-10-9. Since you are at 8-11-9, who knows what chips those are.Quote:

IMO, you got what you paid for. Buy better ram if you want better performance.
As far as your "x86-64 Windows is crap" opinion, what exactly makes it crap? It's lack of 16-bit application support? Why did you buy an 8GB kit for x86 Windows?
Thanks for the warning! I had no intentions of running them for everyday use anyway, just wanted to see what they could do... :p:Quote:

I suppose it is probably possible to get all of the 32bit stuff working on it right.
I was thinking about this the other day, if for example I manage to compile amdmsrtweaker, then gut it and use it to support a new cmd line program of my own, supporting the stuff I miss, then well, it would get rid of that prob...
I would still have some codec issues though.
Anyways one of the main reason behind getting this ram was so I could learn how to hack the kernel and bypass the signing for it.
None of the 64gb x86 patches work on my os, it's not pre-sp1 ultimate or anything like that, so I gotta patch by hand (tried both the german and russian patches and both don't work on my os).
Kitguru had a pic of my rams ic's, there were hynix h9c.
It doesn't mean that's what I have exactly though, I'll take a look at them soon though.
Seen a guy's cpu-z validation at 3600mhz (maybe it was 3ghz or 2.6ghz., I can't remember) with 13t timings.
I don't expect anything like that on my setup, but it sure would be nice to get something like 2064mhz.
Would love to get 9-10-9 timings...
It boots and everything like that but isn't stable.
It isn't stable with stock settings with 9-9-9 at 1600mhz btw.
And I don't know which stick is the best out of the pair yet either, so I don't have them arranged correctly most likely.
(best furthest away from cpu)
in most cases is up to 1.9V OK (LN2 too). No more voltage need for better scaling at RAMs.
Do the 6100 FX have as strong an IMC as the 8120/8150?
Its pretty same as 81XX lineup

Even though my mem clocking skills are a little weak, the 8Gb kits I've been trying lately have gotten me pretty frustrated, so I've been pulling out some old stuff...
The last few days I've been playing with the Corsair GT 2000/CL8 kit. It did pretty well on Deneb, but I had trouble with it on Thuban and the FX.
Anyway tonight I gave up on it's 2000 8-8-8 rating (and the 1866 divider) and tried tightening timings @ 1600. :p:
The results were actually half way decent. Either the board/mem or chip seems to like the 1600 setting much better!
It's only a 15 minute Blend stable shot (Custom/3Gb usage), but I didn't go easy on it (surfing the web and listening to tunes while running) and it seems pretty darn good. :up:

Thanks for the advice Zeus (and Beep)... :yepp:
Finally got the Hypers stable on the 8120 with decent clocks & sweet timings!
I can live with this for awhile... :D

Command rate is 1T. I had tried 2T and it didn't offer any real advantage (@ 1866 anyway... Haven't messed with it @ 1600).
What really seemed to open them up for me was switching to the 1600 divider.
I just set them to 1600 7-7-7 and then brought the HTRef up until they started failing.
They just play alot better @ 1600 compared to 1866. :yepp:
yes that's true I have noticed before and forgot it, anyway gigabyte doesn't have too many subtimmings options just the basic ones, wich I used to set them at 4-4-4-8 or 5-5-4-10 trfc at 90ns or 110ns none of them seems to change stability by muchQuote:

I have PSCs, HCF0s, and Crucial 1.5V 4GB Dimms that Im compairing to each other with a Sabertooth and 8120.
Havent done anything with the HCF0s, but the Crucials do 2000 8-8-8-24 and 2200 9-9-9-27 stable with 1.6375V or less. The PSCs I couldnt get to post at 2200Mhz with 1.65V and even 8-10-8 timings. At 2000Mhz, the best I can get with 1.65V is 7-9-7-24-1t. I dont have time for 32m testing of each kit, so Im just running 1m and 4m. These pics compare the PSCs at 2000Mhz 7-9-7-24-1t and 2t. There is barely any advantage with 2t. Obviously if you can run 1t at the same speed you are limited to, then do so, but if 2t allows more speed or tighter timings, then its worth it. Going to go back to the Crucials and run them, then try the HCF0s.
(for some reason CPU-Z is not showing 1t/2t)

Crucial Smart Tracer 1866 999 1.5V kit at 2000Mhz 8-8-8-24-1t, Spi1m is a little slower then above, but 4m is a bit faster.
Attachment 124363Attachment 124364
With tRC set to the SPD rating of 47, 1m was a bit faster (and tied the PSCs result above). From the thread on these, and this tests, it seems they are more stable with a tRC of 47.
Attachment 124365
Smart Tracers @ 2000Mhz 8-8-8-24-2t tRC 47, 2t seems to show wider results for these then the PSCs above.
Attachment 124366Attachment 124367
Smart Tracers @ 2250Mhz 9-9-9-27-2t tRC 47, pretty disapointing how it just tied the above. CPU speed is a tad slower though, tried to get the CPU and NB/HTT speeds as close as possible.

More here:

Working on a 16GB kit now and its looking good as well.
Mav2000, those pics are way too small to see (at least for my screen anyway). What are the rest of the timings?
Funny, they dont seem to expand on clicking.
The timings are : First one 2,250 Mhz CL 9-11-10-28-45 1T
Second one: 2,333 CL 10-12-10-28-45 1T
Have not played with any of the timings except first 3.
Seems Crucial 1.5V 4GB dimms are still best.
Just something I want to share with you guys as I had a few minutes to test yesterday:
2 x 1 GiB D9GTR (Cellshock CS3222580) + FX-8150 + Crosshair V Formula (UEFI 1102) was really disappointing. I didn't expect any miracles, but the best I could pull of at Prime 95 Blend (custom) was ~ 700 MHz (DDR3-1400) 6-5-5-15. No boot at DDR3-1600/1866 no matter which Vdimm (tried from 1.65 V up to 2.1 V), vCPU-NB (tried from 1.2 up to 1.35 V) or main timings (tried up to 10-10-10-30, 2T). Is Bulldozer really that bad for good old D9GTR or is it me to blame? Have some of you used D9GTx + Bulldozer and what's your experience with it?
btw when going from 2.0 to 2.1 V (no mercy with the IMC :hehe:) I noticed memory detected from CPU-Z decreased from 2048 to 2012 MiB and it wasn't possible to change the reference clock with AI Suite anymore (changes had no effect). At 2.0 V and lower values everything was normal again.
I know this Vdimm range is not recommended for FX-CPUs, but it didn't work properly with 1.65 V before, so I was curious what would happen at usual voltages for D9GTx-ICs.
IMHO it's more likely because of poor BIOS support.
Micron D9-KPT works quite well but not as good as on intel 1155 or 1366, anyway i managed to pull 2700 or 2750 MHz with 2.2 volt or something like that on C5F and FX-4100.
on the other hand Micron D9-JNM doesn't post even at default settings, i've 2 or 3 kits of Crucial value PC3-8500 c7 and they refuse to post with this setup.
hypers are still my first choice with this platform, 2300 MHz 7-8-7 is quite easy.
Hmm, I'll give it a try with my 2x1GB D9GTS, both are Crucial Ballistix donated to me by chispy.
@Mafio
2300 7-8-7 with what Hypers?...my SuperTalent ProjectX dont scale with tRCD +1 but I can run tRP -1. I can't pull off 2180 7-7-7-21 or 7-8-7-22 at 1.8v but I can easily do 2133 7-7-6-20 @ 1.75v which seems to be my sweet spot for example. I'm sure if I went cold with DI or LN2 I wouldn't have issues pulling 2200+ 7-7-6.
I run 2172 8-8-7-24 1.64v with my Hypers 24/7 @ 2560 CPU-NB (unstable). 2600 CPU-NB is way too unstable on this CPU to be usable. My PSC do 7-10-7 at the same frequency and voltage.
wait wait, i'm talking about benching, not daily use.
2300 7-8-7 for benching is easy with both g.skill 2133 and kingston hyperx 2000 c8 i have here.
What voltage then?Quote:

Like I said, my STT ProjectX don't scale with tRCD +1 and I can run tRP -1 about the same as I can tRP = CAS however without (I'm guessing) 1.85v I won't be able to do 2200 7-7-6.
I've been accumulating alot of mem lately trying to find the best ram for FX chips.
So... I decided to compile my results into one post showing the best I've been able to get from each kit while maxing out all components of the system (including IMC, clocks and timings).
At the same time maintaining overall stability (at least 30 minutes Blend max mem stable), and good for 24/7 use. ;)
To be honest, I'm still trying to figure out what all these numbers mean myself, but, I have a decent collection (using various IC's).
FWIW, I'll list them by order (of my preference) and let you folks decide for yourselves.:p:
#1
G.Skill RipJawX (Hynix BFR?) 2133 9-11-10 8Gb (2x4) @ 2222 9-11-10 1.6875v
This will be the kit I stick with for now and runs very solid at these clocks without quirks!
It also gives me good balance and the best core clocks (plus is 8Gb :D):

#2
Mushkin Black (PSC ?) 1600 7-8-7 4Gb (2x2) @ 2038 7-10-7 1.675v
This kit has been a staple for me and is still one of my favorite kits... Honestly, it only loses to the RipJaws because it's only 4Gb. ;)

#3
Corsair GT (Hyper) 2000 8-8-8 4GB (2x2) @ 2000 7-7-7 1.70v
This kit offers up some really good numbers (especially in WinRar), but even though it will Blend at these clocks it still has some quirkiness to it.
Sometimes it hangs on post and crashes when encoding video... :rolleyes:
This was a great kit on Deneb, but honestly, I feel I've given it enough chances on Thuban and Zambezi and its just too unreliable IMHO...
http://i30.photobucket.com/albums/c3..._GT_Hypers.png
One thing I've noticed while pushing memory is a serious drop in L2 read speed when you go too far...
Does anyone know if this is just a quirk with AIDA64, or is it a legitimate problem with FX chips?
I haven't really tested this, but it seems like it may be legit and somethng is trashing L2 performance. :shrug:
Just so you know, wprime has nothing to do with memory. In fact, most the time I bench it, its better to have slower mem speed and looser timings for wprime.
Thanks Cecil.... I only ran the 32m Wprime to show some amout of stability.
All those clocks were >30 minutes Blend (max mem) stable, I just didn't have SS's to show it, and I didn't have hours to waste. ;)
1. Great!...awfully slow but a lot of ram. Middle of the line with 8GB now that the Crucial/Micron kits have been released.Quote:

3. Again decent, but not great. Corsair binned their Hyper tight and unfortunately that's about the worst out of them. GTX2 however, does 2133+ 7-7-7 at the same voltage. I don't think its a matter of being unreliable, but you are trying to push the envelope too much on a kit that's not up to snuff. You should try CL8 or at the very least 7-8-7 IMO. Hypers IMO are the best benching ram for Zambezi. I guess they have some trouble with Llano.
As far as not having hours to waste, set the CPU to something that won't catch fire and "set and forget" as you sleep or go to work.
That should run fine, because some minutes ago I've put 2 x 1 GiB Crucial BL12864BA2009-8SFB into the setup and have no issues at all. I could boot DDR3-1600/1866 at the very first try and now I'm running Prime 95 Blend (custom) at 1,000 MHz (DDR3-2000). So it seems to be an issue with the Cellshock sticks - related to the SPD-EEPROM maybe.Quote:
