Which sSpec/revision ?

storm-chaser · Sep 1, 2018

SLAN6

Earlier stepping, however, this will be going in my HTPC so super overclockability is not required.

Scratch that!!!!

We got the QX6850 running in the Slimline after BIOS update. The trick was AFUWIN.exe from command line in Windows 10!!!

So here we are at 3.0Ghz across all 4 cores!

I should hope it would at least run stock :nutkick:

Yeah you know it's going into my HTPC, right? I was just super excited that the modded bios worked and now I have this great little 3.0Ghz Quad core powa-house for fun in an HTPC sized case.

The computer had originally blacklisted the QX6850 from working at all... that's why I posted the stock CPUz specs once I got the system online with the modded bios.

Such insane FSB clockspeed. :eek:

Damn it is amazing how the humble front-side-bus is approaching intel first generation core i quick point interconnet(QPI) like in i7 920 cpu! I am sure the transfer rate would be pretty close!

No, they wouldn't be.
QPI usually* doesn't do IMC/DRAM transfers at all, it only does PCI-e and by extension, DMI I/O (multi socket communication as well in servers). FSB on the other hand does EVERYTHING, always.
Here's my OC'ed QX6850 in GTA V (with 4k) : LINK

*exception : Clarkdale stuff (where it does both L3 and IMC transfers)

Here is my new Q9450S running at 3.8Ghz. Already going higher than my Q9650 in the FSB department.

Approaching the 4.0Ghz barrier...

Here we are at the magical 4.0Ghz mark...

Good job

Is it stable ?

Im "working" on getting it stable. It does fail one benchmark in the AIDA64 suite, so it's not perfect, yet. But considering we can get to 500Mhz FSB I am considering this a partial win, at least for now.

agent_x007 · Sep 8, 2018

I would try increasing tRAS to 20 or 21 (15 is kind of tight for 1600MHz+ of course if stability problem is ralated to memory).
What FSB Termination Voltage you set for 500MHz ?

I have it currently set at stock voltage and so far so good. I guess I might have to start bumping up the FSB Term voltage soon... I like these memory centric overclocks. Makes for a far more robust setup.

In a search for low profile coolers I came across the Reeven Brontes on Newegg - a quiet 100mm low profile CPU cooler with 4 heatpipes for ITX and HTPC.

This will go perfect with my build and should be the final ingredient in making this system run cool and quiet. Cooler is about $35 shipped. Should keep my QX6850 under control...

Enjoy some picks of my QX6850 build! I will update with more photos once I get the new CPU cooler installed.

Well guys, looks like I'm still being bitten by the LGA 775 bug.

I just ordered an E8600 and about 5 additional CPUs to test out in the benching rig.

Updates and pictures to follow. Stay tuned!

Awesome thread. Almost makes me regret I sold my old Q9450/X48 rig last year (though I god a good 8-9 years out of it, so no complaints!). I'm impressed by you getting it to clock that high - mine topped out at 3.52GHz (24/7 stable) with a Hyper 212 Evo (IIRC it didn't exceed 85 degrees under load). That didn't entail more than setting the bus speed and increasing the VCore a bit, though. I got into Windows at 3.6something, but it crashed running a benchmark, and I couldn't be bothered tweaking it into stability. How much time have you spent tweaking this to get it that high? Whatever the effort, that is really impressive.

Hey thanks for sharing! You know I was about to give up on LGA 775 until Johan sold me a solid benching board, the Asus P5Q3. This really has allowed me to turn up the wick on these cheap and plentiful CPUs. Like I said I have another 6-7 CPUs inbound for testing purposes. And hopefully down the road I will get a big water cooling setup and then we turn them up even more.

If you keep an eye on eBay you can find some great deals. I paid only $14 for my Q9450 and it's been a fun one to overclock

I've spend about two hours getting it dialed in and I'm not quite finished yet.

Hey guys. Just wanted to provide you with an update of sorts. I've recently finished up the QX6850 build and it now sits in it's final form on my desk.

The HP slimline started life with a Pentium E5800 and has now been successfully bios modded and updated to work with the QX6850 CPU.
