i have the patriot memory 1gb stcks and 512 sticks ( dual channel kits) but i bought the cas4 version which are made with the new micron "fatbodys". the cas5 sticks use the Elpida IC's and Powerchip IC's. those IC's are terrible and are not overclocking friendly at all. unless you get the higher end sticks like 9200's, you'll get handpicked micron IC's for those. from what ive seen in other forums from people that have bought sticks like A-data and corsairs that use Infineons IC's, they had nothing but burnt up sticks on the 6xx chipsets. glad to see its working out for ya, just tryin to give ya a heads up about those though. keep us informed cause i would love to see how long they last and especially if you start overclockin them!! good luck and hope they work out. ----------- ACID ----------

I don't have any app that will use 8GB of RAM. The most RAM that one app (among what I have) could use is probably 2GB, and that's under the worst case scenario. Those apps being games and Virtual PC. The reason why I decided to make the trade (sold Crucial sticks and use the money towards bigger capacity) is, however, Vista's SuperFetch. SuperFetch, in its current state, is by no means perfect, but I surely think the trade was worth it.

I've had enough experience of memory overclocking on C2D platform and it was time to settle down and make the machine for actual work (and play). As a matter of fact, while I fiddle with C2D (and now C2Q) my main rig has still been the trusty DFI LanParty board. Although fast, various C2D platform I experienced in the past wasn't just stable enough. But I think now is time to comfortably switch my main rig.

I've finished a 12-hour session of Memtest with 8GB RAM @800MHz/4-3-3-9-2T/1.95V without a single error. I appreciate your advice - I won't abuse these sticks or overclock any higher.

What kind of problem did you experience? Notice my sticks aren't meant for overclocking. Indeed I am glad that these are doing 800MHz/4-3-3 with a minimal voltage increase. I tested one of them just to see what they're like and the max frequency it did with CL4 was somewhere around 880MHz.

OK the demo wasn't anything special. Basically 5 aircrafts are handled by 1 core. Average CPU usage per core is 70%, typically ranging between 60~80%. Exception is Core 1 and its usage is higher than the rest, fluctuating between 70~90%.

5 enemies -> can be handled by 1 core
10 enemies -> 2 cores needed
15 enemies -> 3 cores needed, but 2 cores can handle them with frame rate hit. (no slide show)
20 enemies -> 4 cores needed, but 3 cores can handle them with relatively small frame rate hit (5~10 FPS less). 2 cores or less will generate a slide show
25 enemies -> probably needs another core but 4 cores can handle them pretty well just like the above examples

With the ideal number of cores/enemies, it looks like I'm limited by the GPU.

I also installed it on XP (32-bit) and noticed a significantly lower performance. I've just run it once or twice so it needs further testing to confirm, though.

I just wish we could somewhat control what it caches, or at leasy clearly see what it's doing...
Very good point. I thought about it, too. Indeed if the OS let us control and see the cached files/folders, I would've been content with 4GB performance (i.e. overclocking) RAM.

One last update in this thread.

To be on the safe side, I've got myself the OCZ memory cooling kit. The sticks didn't really get hot without it, just ever so slightly warm. But I thought I'd treat them nicely with a colorful decoration. They look pretty cool. I now just have to put these in a case.

Why would you need to see? You should know what it's caching...

First and foremost, your web browser (and IE if it's not your default browser), Media Player, and from there, ANY application that you open in that order until it hits the physical memory limit.

Superfetch is not doing it's job unless it aggressively caches every last byte of memory you have. Keep in mind letting it cache isn't going to reduce your performance much at all, as it's very passive (passive-aggressive... lol I made a funny) and will happily free as much memory without paging as soon as a page-fault is detected on a non-executed application that has been cached.

lopri,

I was suffering crazy system instability. This board does not enjoy ddr2-800 ddr2-1000 in all four memory banks without some voltage and still it's not stable - rock solid with two sticks. I'm waiting for bearlake and just gonna let go of this board entirely.

Yea, but what if, say, you don't want your download folder to be cached, but rather have your games' installation/data files cached? (which is probably a scenario many would prefer) One might argue that Superfetch will 'eventually' adapt the usage pattern, but without seeing it transparently, one can't really be sure how effective the caching mechanism is. (I actually suspect that's why MS doesn't show the way SuperFetch works clearly - they must be constantly updating its efficiency)

On the same line, if I could control exactly what I want to be cached, I would probably be content with 4GB. Think about it. I think it's pretty obvious that you're the one that best knows about your computing scenarios, and if you can control the SuperFetch the way you want (other than whatever is necessary for its core functions), you're most likely to be able to improve the efficiency of SuperFetch.

I'm assuming 'system instability' is something that's presented in the form of BSOD, System hangs, Application crash, OS corruption, etc. Am I correct? Do you experience such symptoms under, say, 'system default' or 'fail-proof settings' in the BIOS? (i.e. with no overclocking)

P5W-DH specifices up to 8GB of memory support and 975X itself is capable of handling even more amount of memory to my knowledge. I'd think there is a room for trouble-shooting. (Besides, while P35 is new and may be a little faster than 975X, 975X is a hell of a chipset. Its PCI-E flexibility itself wins me over the X16/X4 fixed P35) If all else fails, I'd sue ASUS.

Well, jokes asides, I'm sure you've tried pretty much everything. The blame should be on ASUS obviously. I wish you the best luck with the next board!

Quad Prime95 64-bit LargeFFT 2 Hours (Stopped)

4x Prime95 at 3.2GHz at 1.36V Vcore and only 46C overall CPU temp under load? Seems to me your case has its side panel off or you have some very fast 120mm fans blowing air inside and out.

In a close case your overall CPU temp would be about 72-75C.

1200rpm on the heatsink fan doesn't make it believable either.

So admit it, you're running in an open case next to a window with fresh air?

Where do you see that?
I see 44-49 idle and 62-68 load.

You must have read my post wrong. I was implying his temps seem to good to be true and realistic in a closed case setup. I have a QX6700 and can attest to how much heat these things produce.

GFORCE100: It is mentioned several times in this thread that my system is not inside a case yet. And I made this thread to find out whether running 8GB of memory is possible on current 680i board. If interested, you can see more about my current system in this thread, where you can find a pic of the outdoor rig.

Well.. reading again your replies makes me think that you're possibly replying to some other thread? It's the very 2nd post of this thread where you can find the rig is not inside a case yet. And fan is a 1800 RPM ThermalTake fan.

In that case sorry, I didn't read all the posts in this thread.

Tell us how you go inside a case as this is what we all want to hear

Where did you get prime 64. I had it runing (1 month & a hard drive ago) l had to open only one instace of it and acuratly tortured both cores of my cpu in a split window.

I just download the new offical release And I can't install "warning this is not a 32 bit app"

Are you runnig 64 bit vista or xp? if not, what vers. of prime 64 are you using

Thanks Croak

I didn't save (and can't remember) the original link that I found this, but from the readme file, it's somewhere @www.octeam.fr. I've uploaded a mirror so others can grab it if needs be.

OS is Vista 64-bit. You shouldn't have to install anything to run Prime95. It runs off a batch folder.

I have 2 4gb kits of Patriot ddr2-800 5-5-5-12 ran wonderfully till I realized one of the sticks is bad =\ Even six works great. RMA'd one kit should get back soon I hope =\ I want my 8gb of ram!!! Going to be nice when the q6600 price drop happens and I can pick it up for 266 oc to 3.2ghz hopefully and have 8gb of ram. mmm just thinking about 4 encodes going at once makes me drool.
