Foxconn Quantum Force Black Ops X48 OC Guide (56k Warning)

[quake6]

I'm not sure,but I saw a lot of score with that memory on 2000 with the same revision as I have...

[Xello]

Have you tried changing NB GTL? This was vital for me but i'm not sure if it's because i'm on a Quad. How high vdimm? Here is some of the info Raja sent me, some of it might be useful:

The trade off in the Samsung based parts is that they don't really like anything below CAS 9, without requiring judicious levels of voltage. Running CAS 7 curtails the prospects of outright memory bandwidth (hence FSB) on these chips.

To add some stability into the mix you can also set 6,8,3,6 for the R2RD (Same), R2RD (Different), W2RD (Same), W2RD (Different) settings, though at a bit of a performance hit

Make sure you use slots 2&4 for the memory for a start.

SAmsung memory does not like high Vdimm for prolonged periods - I never use more than 2V on it as I doubt it qould last long. In fact, while we're on the subject I have their 1GB modules here and they actually clock worse over 2V Vdimm - go figure.. If running at CAS 9 where the modules are desinged to run you should fiund yourself getting returns at just under 2V. this is to do with coming into Jedec spec and also gearing up for the on die IMC of Nehalem which demnds the use of lower reference volatges such as Vdimm VTT.

Having to skew a signal depends mainly on 2 factors, the first is due to a mistmatch in motherboard PCB trace lengths. The second is down to a heavily capacitive load stressing the MCH signal output devices to such an extent that waveform slope/hold/fall times become distorted and affect slot to slot data acquisition times. The heavier the capacitive load of the memory modules, the more likely this situation is likely to manifest. When it comes to the Samsung modules (even in 2GB format), they represent a very easy load for the MCH to drive, so generally do not need signal skews when operating around the 1800Mhz mark

Sounds to me like the clock skew values are what you need to be looking at, but i have no experience myself with memory clocks that high.

[quake6]

I doubt GTL would help me... I'll get Cellshock 1866 for about 2 week so we'll see what was problem... Also next week another BO is coming so I'll give it another try...

mhhhh good to read some or rajas work
its refreshing somehow
i like how he explains things quickly and gets down to the point right away and doesnt write endless essays

I doubt GTL would help me... I'll get Cellshock 1866 for about 2 week so we'll see what was problem... Also next week another BO is coming so I'll give it another try...

how about the dll adjustments, did you play with them at all?

looking forward to the cellshock results!
why are you getting a second BO?

[gmcg]

Thanks for your honesty there gmcg, it's much appreciated. I've been looking into quite a few boards, but I did call the XFX distributor here today re another 790i, and they reckon they'll have some in next week. Whether I'll be as lucky next time, who knows???.. Need to sleep on this

Thanks again.
RLM

RLM, I have changed my mind and returned 4780x2 back to the store. There are two problems for me - first one it is too hot, the design is pretty limited for overclocking such as second GPU is getting 96C even being idle. Some people increase the fan speed, but 60-65% idle is too loud for me, as they recommend.

9800GX2 being watercooled and overclocked, gives almost the same FPS, but it is pretty silent without the stock fan - of course. I will continue to use it for a while, even at 1920x1200.

According to Mr. Natural's (EVGA forum) recommendation I have replaced my expensive Corsair 1800 memory (D9GTR) with inexpensive 2Gbx2 Crucial PC-8500 (1066, D9JNL), at 1.95V it works even better. Mr. Natural had been able to run it at 7-7-7-20-1T@2000Mhz@2.0V ... I haven't try this mode yet, but I know I couldn't boot with Corsair at CLS7@2000MHz no matter which voltage I have used - though I didn't even try more than 2.1V.

I still can't believe that once I have paid $622 for 2x1Gb Crucial DDR3-2000 (D9GTS), which is worse than $400 Corsair 1800C7D and this Corsair kit is worse than $75 Crucial DDR3-1066 (D9JNL) ... either Crucial is mad, DDR3 market or Mr. Natural ... with me as well.

And I am also thinking about trying 790i FTW, Blackops is nice, but Nvidia's stuff is going down in prices so fast ... $250 for FTW is not a bad option to try ... may be they have fixed that instability issue.
No, most probably I will stay with Blackops and wait for x58 Foxconn board.

[saaya]

glad you decided to stay

regarding the memory, well for high end memory you usually only pay for 3 things:
1. service+support
2. nice heatspeaders
3. guarantee for high clockspeeds/tight timings

if you know what chips to look for you can usually get close to the same results, sometimes even better, by grabbing a kit of value memory with the same chips.
BUT, the main reason the cheap crucial stuff does well is cause its newer... the other kits are older, and the recent d9gtr chips from micron are getting better while the other mem was probabaly made in a time where there were no good gtr chips around or there were no gtr chips available whatsoever

[quake6]

I think 2000MHz is possible even without dll adjustment, but yes I did some dll adjustment and again nothing... Thinking that memory cant go 2000 stable...

It is from my friend... Then we will see what is problem and I'll test it also on 790i...

[saaya]

ok, let me know how the mem does on the other board!

[rgkpt]

Foxconn get good BIOS

[saaya]

Foxconn get good BIOS

you mean we have a good bios or you mean we should improve the bios some more? i guess both is true

[Xello]

Foxconn get good BIOS

Lol, how random.

And I am also thinking about trying 790i FTW, Blackops is nice, but Nvidia's stuff is going down in prices so fast ... $250 for FTW is not a bad option to try ... may be they have fixed that instability issue.

Heh something tells me you don't want to experience that all over again...

[Catz]

Foxconn get good BIOS

Explain what you mean or be quiet

[gmcg]

glad you decided to stay

Thanks, saaya, how can I leave such a good company?
Please let some people beta-test x58 to make it perfect and make a retail version above any expectations ... ; iphone 3G is a good example (I have never spent 2.5 hours in line buying any electronics before, and what is interesting, I don't even regret)

True, but Crucial - how could they use D9JNL in low end value memory and use D9GTS in a top-uber-most expensive kit, I simply didn't get it. Crusial in my mind was always an engineering company, not a marketing company, and now ... I love their DDR2 PC6400 chips, and I love DDR3 1066 D9JNLs, but I would never ever buy their "top-of-the-line" products, period ... Their service is not different for value modules and top modules, isn't it?

If it can do 7-7-7-20@2000MHz at all, it can definitely do 8-8-8-24@2000MHz (or even 8-7-6-24) stable, don't you think so? I will post results a bit later, but for now: http://www.evga.com/forums/tm.asp?m=...55651;� "Shock-the-Monkey" is a new nick of "Mr. Natural" ...

Heh something tells me you don't want to experience that all over again...

LOL, you are 100% right, Xello ... I simply forgot about that time ... I don't want it.

Hi All,

I just got my Black Ops system up and running, easy as pie but it is not overclocked yet. The processor is a Q6600 G0 SLACR, memory is a pair of OCZ PC3 12800 (OCZ3P16004GK), 7-7-7-24. Can someone suggest overclock settings? I'm a bit confused because the bus is only 1066.

To the posters with info on defeating the fans for water cooling, thanks much!

Jeff

1.5vcore
400fsb

GO GO GO

After that start tweaking the vcore lower and lower and lower until it's not stable anymore

working on it

True, but Crucial - how could they use D9JNL in low end value memory and use D9GTS in a top-uber-most expensive kit, I simply didn't get it. Crusial in my mind was always an engineering company, not a marketing company, and now ...

Their service is not different for value modules and top modules, isn't it?

gtr/gts costs more than jnl and people want gtr/gts cause it scales better with volts and tey get slightly higher clocks (50mhz)
thats for the top bin parts tho, if your looking at 1800 and 1600 yields at low vdimm, then JNL beats the big chip micron stuff...

So you mean that there is a difference in batch for memory chips, such as it is in CPUs? Thanks, I didn't know that.

h3ll yeah! for ddr2 it wasnt that big, but for ddr3 its enormous!
the best batch large chip ddr3 stuff from micron clocked amazing, 1800 cas6 yield of 50% or more! later batches had a 1800 cas6 yield of maybe 3%... some 0.00%
the funny part is that the lowest micron bin clocked the same as the highest micron bin
even now the jnm clocks the same as jnl... microns binning process kinda sucks... i had a conf call with their engineers when i still worked for cellshock and they said they would try some new approach but from what ive heard it doesnt seem to work well... idk how exactly they bin, but its not doing much and the actual real world max speed is about the same for all bins.

for ddr2 the differences were not that big. some batches were VERY sensitive to voltage tho... the earlier batches scaled with up to 3v and beyond, the later ones stopped at 2.4v sometimes and wouldnt scale at all with more vdimm... earlier ones clocked very well with cas4 and cas3, the newer ones clocked high with cas5... theres def a notable difference with mem chip batches!

look at the BH5/BH6 database thread i created years back
search the forums and youll find it

If it can do 7-7-7-20@2000MHz at all, it can definitely do 8-8-8-24@2000MHz (or even 8-7-6-24) stable, don't you think so? I will post results a bit later, but for now: http://www.evga.com/forums/tm.asp?m=...65533;� "Shock-the-Monkey" is a new nick of "Mr. Natural" ...

if it can do 777 at a speed it can do 888 at the same speed as well, but some chips only like high volts with tight timings, so 2000 888 might be unstable with the same vdimm that is stable with 2000 777
and the newer micron chips dont like tight trp and trcd, they love 777 888 or maaaybe 776. check my older threads in the xtremebandwith section when i still worked for cellshock, i posted the timings the chips prefer and how much mhz they scale from each timing etc in several threads

LOL, you are 100% right, Xello ... I simply forgot about that time ... I don't want it.

welcome to XtremeSystems Jeff!
ouuuuu sounds bad, looks like your cpu is a slackR

an alternative approach:
first of all make sure all is cooled well and doesnt get above 50C.
60C is ok, but thats really the max you should accept, try to keep things in the 50C range or below!
pull down the cpu multiplier and pull out the memory from the equation by giving it the max allowed vdimm and setting it to 888 or 999 timings.
now the only thing limiting your fsb overclock should be the fsb/chipset itself.
increase vtt bit by bit and see how high you can get the fsb.
bumping up nb voltage and vcore might help as well to get a slightly higher fsb, and pll volts can help too. gtl settings later, those are fine tuning....

once you know the max fsb, set the fsb to default, pull up the multi to the max, keep the mem slacky like before, and then pull up the fsb bit by bit again, bumping vcore, to find the max cpu clocks.

once you know max cpu clocks and max fsb, you know what multiplier/fsb combo to aim for. remember that max multi will not give you the same high fsb as the lowest cpu multi! you always lose a bit...

once you got the cpu dialed in, all you need is fine tune the memory.
OR you can spend more time fine tuning the cpu by playing with pll, vtt, nbgtl, cpu gtl etc to squeeze another 10+mhz fsb out of the cpu.

have fun!

Hi all...

I was planning on buying some more memory to make a 64bit OS. My question is should I buy another 2 x 1Gb sticks of the G Skill 4 X 1GB sticks =4GB. I am running them at 450FSB 1800MHz 8-7-7-18 1T. Do you think I can run the same speed with 4GB? Or should I look into the 2 x 2GB stick = 4GB and go that route, and which one should I look at?

Thanks for your 2 cents..

[saaya]

if you dont mind tweaking it, go for 4x1gb, if you want a plug and play setup, go for 2x2gb
afaik 4x1gb clocks better than 2x2gb. if you find good 2x2gb itll clock as good as 4x1gb, but those good 2gb sticks are hard to find and expensive i think.
then again, you might think about the future and go for 2gb sticks already cause you will want 3x2gb on nehalem

i personally would bae my decision on the cost factor...
if i have time to tweak the mem then id get the extra 2x1gb
if i dont have time and can find good use for the kit i already have or sell it easily, and the 2x2gb kit doesnt cost that much, then id go for that option

[quake6]

I tried this board with 2x1gb Kingmax 1333MHz JNL chips. With one stick it boot normally (no matter what stick I use), but with two it wont boot. I always got 54 code with beeping. Tried in DC,non DC and it's the same...

Anyone?

And also,does anyone know measurement point for CPU,DRAM,VTT,PLL,NB,SB?

Make it Vdimm=1.9V and you will be able to boot.

[quake6]

But I cant go into BIOS to it change into 1.9v... When I put another stick,my BIOS reset and cant boot...

[Ryan12]

So you put 2 sticks in and it resets all bios settings?.... shouldnt vdimm just apply to the whole 4 slots? I know the blackops does that..

[quake6]

Dont know for BO,but for DFI it does... I'll give it a try now

[gmcg]

But I cant go into BIOS to it change into 1.9v... When I put another stick,my BIOS reset and cant boot...

Try to set 1.9V in BIOS with one module and then insert another one.
