djt01 is correct. After changing all those components you need to reformat. But look at it as a good thing, you get to start from scratch! Its tedious but you get to eliminate all the bogus software you never really used or drivers.

Hi Nick, Jordanal.I have recieved my ASUS P6T Deluxe V2 board and 6GB DDR3@2000MHz Kingston 9-9-9 tripple channle kit.I am still waiting for the d0 Spec 920 :o .For my cooling solution I purchased the Prolimatech Megahalems (www.prolimatech.com) and mounted 2 12cm Fans with rubber pins (i don't know how they call them) on each side of the HS. This HS came first in cooling performance at http://benchmarkreviews.com/index.php?opti...5&Itemid=62. I also wanted to purchase the Thermalright ultra 120 but it was out of stock in my country. Only the socket 775 edition was available.So what do you think? Am I going to be able to clock the 920 to 3.5-4.0 GHz range? Even 3.5-3.6 will be acceptable for me as long as I get no stutters and a reasonable 30 fps with fluid performance at 1920x1080p resolution. All I want is to be able to match the performance of an unclocked i7 975 :( .One more question: Is there a way to avoid formatting and re-instaling OS and applications once I replace my old board, cpu and mem with the new ones? The reason for asking is that I have so many add-ons for FSX and its going to take days to bring the system back to its current state :( .I am using Vistax64bit ultimate SP2 on a 300GB raptor 10000rpm disk, WINXPx86 SP3 on another 300GB raptor and Win XPx64 SP2 on a third 300GB raptor. Its a kind of multi-boot system but each OS is completely independent from the other two i.e. in order to change OS I enter the BIOS and change the boot disk. This made it possible for each OS to install itself and programs on the disk drive with letter assigmnet C:\ which has a few advantages when installing programs. I have also disabled the other two disks from each OS device manager so there is no accidental deletion or effect on the system disks of the other OSs. I have installed FSX with all addons on each OS so if there is a problem / incompatibility issue with an addon I can track it down easily. Plus its an extra safety measure in case a disk fails. Of course it is a great pain to keep up-to-date 3 OSs and their apps but its my choice. That's why I want to avoid formatting and reinstalling :P .Thanks folks and sorry for the long post :(

Any time I change out the MB, it gets a clean install of the OS, FSX, and all addons. And yes, it sucks, but why spend the money for new performance only to cripple it with a half-baked software install. I believe in a clean, fresh, installation of chipset and bus drivers and so-forth. I do cheat with my AI and add-on aircraft by installing them properly, then back-copying config files, liveries, and AI collections.

Ok folks. I get the message. :( I think I am going to vomit :(I 'll go get my aspirines...

DDR3@2000MHz Kingston 9-9-9that was a mistake tooShould have been 7-7-7 or 8-8-8And running DDR3 2000 on a non extreme processor is problematical, D0 stepping or notYou would have been far, FAR better off on DDR3 1600 @ 7-7-7 (6-6-6 would be even better)

Yup, I think my personal-best record for both boxes this past go-around was 5 straight days, 12 hours a day for a full rebuild of both boxes, including backups and drive-images. Oh, and when I say I back-copy config files, this does not include the FSX.cfg or other FSX specific cfg files. I only do that with aircraft.cfg files, but even then, PMDG is tricky... :(

Oh no... Is it not possible to run this memory at lower latency at 1600MHz?? I thought that when you lower the frequency, you can lower the latency too. i.e. 9-9-9 at 2000MHz and 7-7-7@1600MHz. If I can't do that, then I am going to feel realy :(. Nick can you propose some 6GB tripple channel kits that can be used with the d0 920 and will help with overclocking the CPU @ 4GHz? I will try to return the Kingston to the retailer but I doubt they will send my money back :(. Thanks and sorry for asking so many questions.

You will probably be close to the ragged edge of CAS 7 if you underclock it to 1600. It's going to take you some time to experiment with the timings to find how tight you can get while underclocked to 1600. If you can return the CAS 9 stuff, I'd do that.To underclock, I'd set 8-8-8-24 @ 1600 MHz as a starting point and step the individual settings down one at a time, running a couple cycles of Memtest 86+ each iteration, until it chokes. Then bump it back up one step, run Memtest 86+ again, and if it passes, then at least an hour on OCCT. Mushkin model 998691 is 6-7-6-18 CAS 6 @ 1600 MHz--a 6GB kit sells for a pretty reasonable $180 at NewEgg. If you can get BCLK up to 200 (4 GHz on the 920) you can drop the memory mult to 8 and run it right at 1600. But if the CPU tops out between 160 and 200, you won't be able to run it right at 1600. Might be worth it to wait and see how fast you can get the CPU to run, and then make a decision on RAM based on that.CheersBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO

I returned the 9 latency Kingston 2000MHZ 6GB tripple channle kit to the retailer. They said they will refund me with 276 Euros.If I get the cash I will go for a 7-7-7 1600MHZ Tripple channel 6GB kit at around 150 Euros (200 USDs). I haven't seen any 6-7-6 latency 6GB kit in my country. I can't order from outside EU. USA doesn't ship to Greece. I will google the muskin 998691 and see what I can find :( .At the moment I have only the motherboard ASUS P6T Deluxe V2 and the CPU HSF :( .Thank you all for your input.

Just so you know, my Mushkin Redline was the 998692 model with a default clock of 6/7/6/18 as well. The only difference was the wider heat-spreaders for more cooling. The only disadvantage is a max of three sticks because of the width of the spreaders. That shouldn't be an issue though as anything over 6GB (3 slots- 3x2GB) is probably overkill. This stuff worked great, right out of the box and was a great match to the d0 proc. Highly recommended...Mushkin 998691 or 998692 are basically the same except for the spreaders.

Hi Jordanal. Thanks for your advice. The only problem is I can't find Mushkin 998691/92 or the even better 998729 (6-6-5-18) or the 998675 (6-6-6-18) in my country. I live in Greece and I can't order from USA retailers. :( :( . I will probably buy a 7-7-7-24 Corsair, Gskill, OCZ or Kingston for around 150 Euros. I think I will go with the corsair model Corsair XMS3 - Xtreme 6GB DDR3 Non ECC CL7 1600MHz (TR3X6G1600C7) (Kit 3 x 2048). Thanks again my friend. :( .
