I have been looking all over the internet for some assistance with this particular combo (DX48BT2 and E8500 E0), but it seems like people only have one component, or the other - not both together....Can anyone help out with getting this combo to a stable overclock? I can post whatever info is needed....I already put the major components in my profile.

(Please note: If I had the cash to buy a new mobo/CPU, I wouldn't be asking for help with this setup....)

Found something that might be helpful.

http://www.xbitlabs.com/articles/mainboards/display/intel-dx48bt2.html

I'm not sure it will be helpful in a good way though. Intel boards are generally rock solid and compatible with almost anything. They are also almost always very poor at overclocking if not totally locked.

I did not read the article. This will help you overclock your CPU if the board is capable.

http://www.tomshardware.com/forum/259899-29-core-overclocking-guide

You will need aftermarket cooling first and foremost. I don't have time to help you directly tonight but if you still need help I will be glad to help tomorrow. I ran an E8400 at 4.050Ghz for over 2 years and an E6600 at 3.2Gz for 2 years before that so I still remember my Core2 stuff :)

Yeah, I've read through both of those guides already, and have been through a multitude of articles that talk about "how poor of an overclocker" this motherboard is. However, they also say that it can be done, it's just more difficult to accomplish. I'm asking for help on this specific combo because of the fact that the BIOS for this mobo uses some slightly strange terminology. For example, there is no "vcore" option, it's called "CPU Voltage Override"; instead of NB voltage, there's "MCH/ICH Voltage Override". Things like that start to get sort of confusing when trying to remember the proper settings to change. On an older mobo I had, there was a clear option for changing the RAM divider, which I can't seem to find on this one, so I haven't been able to get it down to the 1:1 ratio that it should be on, which might be part of the problem of overclocking on this board.

So I'll post my major components here also:
CPU: Intel E8500 E0
Mobo: Intel DX48BT2
RAM: PNY PC3-10700 2x4GB
Heatsink: Evercool Buffalo w/ Arctic Silver 5 Thermal Compound
Case: Thermaltake V4 w/ 3 120mm Fans (1 in front - intake, 1 on top - exhaust, 1 in back - Heatsink vents directly into the back one)
HDD: Seagate 1TB 7200 RPM 64MB cache
PSU: Thermaltake TR2-600W

Basically, any article that shows up within the first 3 pages of Google, that even remotely references my situation, I've already been through - as well as whatever search engine my Windows Phone is currently utilizing. I generally don't even post in forums because I can generally find my answers. However, it doesn't seem like many people paired this CPU with this board, which is where my need for help stems from.

UPDATE: I have since gotten my E8500 up to 3.9Ghz and stable....So much for this board being a "bad overclocker"....So if anyone happens to need help with this type of setup, let me know - I'm more than willing to share what I've learned.

Good for you! Sorry I could not be more help but I had no first hand knowledge of that board. I remember the thread though and was going to try to help. I must have lost track of the thread. Glad you figured it out though!

No worries, it would have been nice to have some help, but I seem to do pretty well without it....As far as the things I've read about this board not being a good overclocker, I call BS on all of them....:D The people that tried must not have had the patience for it....It's stable and running fairly cool, considering the fact that my room is pretty warm all the time....Thanks for trying to help out!

(Note: I have Folding@Home running at Medium load in the pic below)

I have the same board and have had a similar experience. If I had seen your post earlier I would have replied when you were asking for help.

I scored this board new in a sealed box for $40 off ebay to replace my old crappy Asrock 775 board in a spare parts build for my girlfriend when she showed some interest in PC gaming.

I have had a q9400 running at 3.2GHz with 400MHz FSB and 1.22Vcore for about 6 months now. When she is not using it it runs Folding@home 24/7. Temps with continuous 100% load and Hyper 212+ are 54degC max.

After I got the board I flashed to the newest BIOS and didn't have any problems overclocking on it.

That's cool....It seems like people just read the articles that said this board was a bad overclocker, then they just repeated what it said....This board is a champ, though I recently learned that Thermaltake TR2 PSUs aren't very good....As my TR2-600W just died after I tortured it for about 10 months. :) My new one has me at 3.95ghz so far, and I plan on getting over 4ghz....I've been looking for a decent priced Quad so I can try those out - I do an awful lot of multi-tasking, and am now running 3 monitors.

Lower the multiplier? You're the first one I've seen say that out of all of the forum posts/guides/articles/etc that I've read....Whats the benefit of lowering the multiplier (and raising FSB) vs only raising the FSB? I have been under the impression that lowering the multi and raising the FSB will only put additional strain on the CPU, thus causing it to work harder than necessary....Is there anything to back up what you're saying?

Not sure what you were trying to show with those links....They show an increase without modifying the multiplier at all (the multi was 9x in both screenshots on there)....I'm currently at 412FSB with my E8500's 9.5x multi....I'm not looking for a crazy benchmark, I'm looking to increase my power for a stable build, since I don't have the cash to go out and buy the parts to upgrade my system to a newer socket type and CPU.

This board is awesome! I honestly think that people just didn't have the patience to actually mess with it, so they went with what some (apparently) biased reviews said about it....I got this board from eBay for $60, and my E8500 for $20 from Craigslist and almost have a full 1ghz OC....

Sorry, but i was actually just in the BIOS and ended up getting sidetracked....:D The highest temp that was reached was 66*C and it is a bit warm in my room....I'm going to wait till I get my full 1ghz OC to start reducing volts and lower temps even more....However, I do need help with my RAM - that's the part that I'm still pretty unsure about working with....

How much more voltage are we talking for the DRAM? I'm using 2 sticks of PNY Optima RAM, so I'm not very confident in it's ability to run in various timings/speeds....This site (http://www.motherboards.org/reviews/motherboards/1791_5.html) has an easy way for me to show good pics of the max voltages for the items you asked about.

So I'm keeping the same RAM settings (reference clock and speed), applying the 5-5-5-16-64 timings, and increasing the VRAM to 1.67? Is that going to work with my RAM chips (PNY Optima)?

**Keep in mind that I'm not striving to set any benchmarking records....I have just noticed that it seems like my RAM is lagging a bit now....

Seems like I might have to get better RAM in order to do any messing around with it, these PNY chips dont seem like they like to be messed with....When I changed the timings, my PC wouldn't restart....

Ok, so I started tinkering with my BIOS again, since it was bugging me that I had to keep my RAM running pretty far below it's normal speed in order to keep my CPU overclocked....I managed to get my RAM pretty close to it's normal speed, plus I gained a little bit more on the CPU side - temps are still really good....I only got up to 66*C while running IBT, normal load temps are about 55*C....

That is a pretty nice OC, is that actually 24/7 stable? What kind of RAM are you using?
