ok i have the iso and burned it to a cd but still cant boot to it or the alt-F2 thing either...i did the pencil mod also but i think i have to do it a little more but that requires me taking off my cpu fan....i now have a project for the weekend!!

OK, so I just ordered another EVGA 9600GT 512MB card today to finally set up SLI. I also just ordered 4 GB more of ram (Same OCZ 2X2048 kit) as well. So now my new system specs are

Intel Core 2 Quad Q6600 @ 3.5 GHz
Arctic Cooling Freezer 7 Pro CPU Cooler
OCZ 8GB (4x2048) DDR 2 800 Vista Edtion
XFX nForce 680i LT SLI
2x EVGA GeForce 9600 GT 512MB in SLI
4x Western Digital 500GB SATA 300 (AAKS)
Apevia Beast Power 680W
Antec P160W Case
Vista Home Premium 64-bit/Windows XP Dual Boot
ViewSonic VX2035WM 20" Wide Screen
APC BR800BLK Battery Backup Unit (UPS)

Does this sound like an OK system? I'm a huge multi-tasker and moderate gamer (not a HUGE game freak.) I figure this system should hold out for a few years I hope. I basically built this system a little over a month ago now and the deals have all been great since almost everything had a rebate. I just now today received my 4th out of 5th rebate and it's only been just a tiny bit over a month. I can't believe I've received all the rebates this quickly or at all. Most of them say wait 8 or 12 weeks, but it's been about 4. I received email conformations from 3 of them as well which is beautiful.

The 4gb kit of ram I just ordered also has another $30 rebate with it so it ended up costing $61 for it. I read the rebate details and also emailed them to verify and yes I qualify for the second rebate since their terms state "One rebate only PER PROMOTION" and plus, I ordered it from 2 different sites at different times.

All this ram will be very useful since I have tons of windows open at once and I use at least a gig for each virtual machine I have open. Any thoughts on my decision? Am I stupid? Is this a decent system? May I run into any problems? Thanks all for your input so far! This is an AWSOME thread with lots of attention it seems

I had to go away for a few days, But I finally got back and decided to give overclocking a first timers best shot.

Went in my bios, unlinked everything turned off various settings so that i could actually manipulate the speeds and set the clock to give me 2.5 instead of 2.4.

save and reboot. Screen went black then came up showing me my processor speed and info and gave me the press delete to enter bios option then sat there.

I believe that means it didn't post?

In anycase after restarting a few times it warned me that it was in safe more and to reset my bios settings which I did.

I've come to the conclusion that I am indeed a noob when it comes to OC and all my reading on the subject apparently didn't help much.

Time for more articles and a round 2.

*EDIT*

Don't know exactly what I did differently, but With only disabling the automatic OC provided by the bios and unlinking, I was able to start up at 2.5

Something odd with CPUz though, it shows my multiplier jumping from 9X to 6X lowing my speed to 1.8 or so.

I did leave all my voltages on auto, which I think is not necessarily a good thing.

*EDIT#2*

So i decided to see how high I could go changing nothing but my fsb.

at 1423 with a 9X multiplier and cpu core voltage at 1.28125 all other voltages on auto it seems i've reached my knowledge limit to pushing this any further. if I try to go above 3.2 i get a lockup same as before.

The reason for your multiplier and speed jumping like that is BECAUSE YOUR MOTHERBOARD AND CPU ARE GOING TO BLOW UP IN THE NEXT 5 MIN!!!! RUN!!!!!

J/K. At first when I got my system mine was doing that too, and it freaked me out, because I saw that speedstep was turned off and still doing this. Then I noticed that C1E was turned on, and that's what's causing this. It's basically a power saving feature. When the cpu isn't under load or it's idle, it lowers the speed, but give the CPU something to do, then it'll jump back up to normal speed.

As far as overclocking, I couldn't go above 3.2 ghz that easy. 3.3, would cause errors, but 3.5 and up worked perfectly. I might have hit that "hole". Remember that when you overclock (raising the FSB) you have to raise voltages once you start seeing lockups and errors. Just play it safe and remember that the more you raise your clock, the more voltage you will need, and that more voltage = more heat. If it were me, I'd keep my speed at 3.2. I just lowered mine to 3.2 ghz and am happy there. For me to be stable at that speed, I need 1.38 on the core, and that ran perfect for 19 hours on prime 95. Temps are around 38c idle and 50 load. I'm happy there.

is it really and truly as simple as only changing the 1 voltage and fsb?

it can't really be that simple. I'm not too worried about heat since the average celcius temp ( for non self built pc's) is around 65C and I'm WAY under that, even under load. I just want to get decent frame rates. I was happy with this pc but the core speed at 2.4 was always bugging me and I even saw slowdowns in places that my old pc didnt see slowdowns. it was a single core 3.0

I don't know. I like to push my machines and get the best I can but that's only when I know what i'm doing and even after reading all i have on OCing, i really don't feel I know anything.

WOOOOOO I finally got my ram and video card in the mail today! I first installed the ram to make sure the system booted ok with all 8 gigs and everything was fine. Then installed the second 9600GT and blah. I was upset because the frame rates didn't change much. Well that's because I would click "Enable SLI" but stupid me didn't see the button on the bottom right corner that says "Apply" lol. So anyway, once I finally enabled SLI, here were some of my results. I'm pretty damn happy.



^^That's Crysis without SLI on max settings (High) in XP using 1680x1050



^^That's Crysis with SLI enabled with same exact game settings



^^3DMark06 in XP 32-bit without SLI



^^ 3DMark06 in XP 32-bit WITH SLI



^^Vista 64-bit without SLI



^^Vista 64-bit with SLI.



^^Just playing around in WoW. The FPS there is usually floating around 240 FPS to 305 FPS at the absolute highest settings that game allows at 1680x1050..






These FPS's and scores are with my video card's stock clocks. My biggest issue now is heat since now it's hotter in my case x2. I'll figure something out soon enough. Overclocked while playing Crysis brought me up to about 60 FPS instead of around stock 50 FPS-ish. Tomorow I'm going to mess around alot more with this and discover more of it's potential. I'm EXTREMELY tired right now and am about to pass out in bed. Lemme know what ya think

Very nice, you make me want to SLI my rig. Depending on how the next few days at work go, I might break down and buy a second card.

I recently got the $399 Q6600, XFX 680i LT, OCS PC6400 Vista Upgrade 800MHz combo from Tigerdirect.
I will try some of the CPU overclock techniques described so far in this thread (currently not stable at 2.87, 3.0, or 3.2 GHz, but haven't fooled around too long with it).
However, my question refers to RAM overclocking for this OCZ RAM. Basically, is it better/highperformance to overclock the FSB/voltage or tighten the timings at 800? I got the RAM stable at 950Mhz @ 2.0v. Haven't fooled to much with it, but I got it up 1000MHz and was stable with Vista, but not under heavy load (Crysis).

It actually might be better off if you run 8*400 = 3.2GHz. You'll have faster memory transfers.
how come you dont have to worry about the RAM overclockings until after them settings ? i tried 355 x 9 = 3.195ghz , and upped the ram to 850mhz. did no change at all when benchmarking. is there like a bottleneck or something that wont give more performance by OC'ing the memory to whatever higher than 800 when doing 9x355 or 8x400 on a Q6600 ?

if its better to run 8x400 than 9x355 , is that because 1:1 is faster ? was checking cpu-z when i did 9x355 , 5:6 if i recall it right @ 800mhz and 8x400 1:1

im a rookie at these stuff , thanks in advance for any answers

i think what he meant was, once you set those settings (400x8, 400x9 etc) or higher, the ram automatically clocks above 800mhz to maintain a 1:1 ratio (if you set it to do so), since the bus goes over 400mhz. (remember, DDR ram must be halved to get its clock speed, the 800mhz is Double-Data-Rate effective). so setting a 400mhz bus with 800mhz ram is 1:1. once ram goes over 800mhz, the standard stock speed for PC-6400, thats when timings need to come into play as the RAM is actually being overclocked.

you should always opt for a 1:1 ratio for maximum stability. to be honest, i've never really noticed much of a difference when overclocking ram, so i've always kept a 1:1 ratio.

the biggest difference i ever noticed was affecting the RAM timings. my ram was able to stabalise 924mhz @ 4-4-4-10-1T timing. setting that as my timings gave me a little over 100 points more in benchmarking every time, compared to running 1066mhz 5-5-5-15-2T.
