Dell E520 qx6700 OC project - Page 3

I cancelled the Antec and ordered EVGA B2 750W. I appreciate the help. I already have a 3.4A. Delta fan in the front of my case, don't need another loud fan for sure.

OK back to the Dell E520 project. Since I was last here I installed the EVGA 750W PSU. It took some doing, I had to eliminate 1 extra DVD burner that was a little too long to make room for it, but it's in. Next I installed the Sapphire R9-285 ITX 2GB DDR5 O/C video card. It has a Dual BIOS switch to run either EUFI, or AHCI BIOS modes. The card has been modified by cutting he bracket in 1/2, and cutting a vent so air goes out the side of the card. It works OK like that, but cutting the 2nd slot in the case is another and maybe better option. The card works great. I'm scoring 1809 in Unigine heaven 4.0 ultra settings 71.0 fps.. up from about 50 fps with the GTX750Ti O/C. There is an issue though. I have support tickets with AMD and Sapphire. I can't enter the MB BIOS. No big deal Dell has it all locked up anyway. It says GPU wont support "video mode 103". So The card fits and runs great, we'll see if I can get the bugs out of it.
Look in my sig. for where the O/C is at now.

Wow cool thread, wish I found it earlier.
I have a "E520" as well. In quotes because it actually was conceived to this earth as a Dimension 5100.
The 5100 was restricted to Pentium 4 only. Pentium D could be run unofficially as well and worked fine, but BIOS gives nag screen with "Alert! Incompatible CPU every time which is super annoying.

So after owning this Dimension 5100 for like, 8 years or something, I took my chances with a used E520.
The E520 was shipped to me I didn't pick it up. To my dismay the seller shipped it in a large box with zero protection.
There was some damage to the case but overall it survived remarkably well.
Worse news came after, as there were leaky caps all over the board near the VRM, and the PSU was making a awful electrical noise when the PC was running, which amazingly it did without any issue.
So, I fixed the capacitors on the board using my soldering skillz, actually I failed the first few times. During these times the motherboard actually ran WITHOUT vrm capacitors biggrin.gif and it worked.
But I fixed it properly after that and have been running it since.

Anyway, because the case of the E520 was knackered, I transplanted the insides into my 5100 case. I had to cut the rear I/O plate for it to fit.
Everything was succesful, and it is running to this day.

Specs: Q6600/4GB DDR2/HD7770

The PC is not getting used anymore though. I tried selling it once but there aren't any serious buyers, only people who are looking to pick it up for a tenner.

So should I do the QX6700 mod? I only have the stock aluminum (not heatpipes...) heatsink.

I wrote an article based on the E520 project at Tomshardware. "Overclocking Dell BTX Computers". I've now moved on to a Dell Precision T3400 workstation project since the E520 was built out.
The QX6700 mod. will run stock speed wiht that cooler. 3.2GHz easily with D9729. At 3.45 you want a QX6800, and over that you need a QX6800 SLACP and a T9303 cooler mod, and other stuff. VRM cooling, Bigger fan mod.
Here's the run down on the T3400.
Native support for Core2 Extreme up to QX9650
16GB DDR2-800 ( this equals DDR3-1066 so don't sweat it too much)
2-PCIe 16x full length, 2 slot video cards in CrossfireX (R series aka GCN AMDs won't display BIOS screen).
375W PSU has 1-6 pin PCIe, 525W has 2- 6 pin. aftermarkets fit.
Native RAID 0,1, 10 support up to 4 drives.
X38 chipset has hidden support for 400FSB (not confirmed on this computer yet).
It's still a locked BIOS project. These have gone 4.16Ghz and with 2-HD7850 scored 7500 in Firestrike.

Another computer you might want to keep an eye out for is the Dimemsion 9200. It's the same as E520 except it has room for 2 slot GPU. It's a Mid Tower, not Mimi Tower
