LGA775 retro OC project

[agent_x007]

Given the ram timings displayed, that isn't likely to be much of a problem if at all. In fact, those are very good timings for a DDR2 based system, so any such number will very likely be good.

Depening on Strap/Performance level used, it may not be as good as you think.
Latency and bandwidth values should show how good those settings actually are.
I consider 60-70ns RAM latency on AIDA64 as good value to have on LGA 775.
Under 60ns is great (very good), and under 55ns is simply awesome .
Example of a good score on DDR2 memory :

Multipliers are weird. If my experience is worth anything, your 445FSB might be stable at 6x, but not at 7x or higher, regardless of what the CPU core itself can do.

Currently testing highest stable (at least for my purposes) cpu speed with p95 small fft runs. The Vcore needed is scaling fantastically well... will post screenshots very soon.

Check memory read/write/latency in AIDA64 for example.

I'll run AIDA64 when highest stable OC with 8.5 multi is achieved with p95 runs.

But so far, I'm very impressed with this "old school" Xeon chip, keeping in mind it has the full 12Mb cache & all this done with 8GB DDR2, compared to the issues I had OC with Q9400 @ half the cache.

The Xeon series of CPU's have always fetched a premium price as they were the cream of the crop of all of Intel's lines of CPUs. They have always been the better overclockers as a result.

That's true... sadly Xeon overclocking is no longer possible since 1366...

 

[agent_x007]

@hat Check Xeon E5 16x0 v1/v2 series

That's Sandy Bridge? Eh, it's certainly not possible on current hardware...

That's for sure, at least back in later yrs of last decade. They dumbed down OC when Sandy bridge came out by locking down BCLK cause' that "useless", at least to performance gamers & OC enthusiasts iGPU.

Revenge of the "dinosaurs"!

Picked up some nice Kingston HyperX 1066MHz 2x2GB kit, will play with those when done with 8GB of Corsair's CM2X2048-6400C5

Edit: My safe limit for sustained p95 testing, at least for my purposes. Nearly 1GHz OC. Satisfied with thermals using Deepcool GAMMAXX 400 + Cryorig QF120, there is provision to install pull fan on this HS but because of the case I'm using in this rig - Deepcool Tesseract, it already has 3 x 120mm fans. I'm not one to overkill with fans.

I'm closing this project. The OC achieved has real world applications as demonstrated in PCMark & 3Dmark benchmarks.
Restoring win7 x64 to system.... & on with the next challenge.

 

[storm-chaser]

Ok, gotta bunch of screenshots here with everything running at stock & verifiable results on 3DMark.com

1st up, PCMark08 on Win7 x64 Home edition.

It's clear to see from the above results that at least with 3DMark & PCMark series of benchmarks, Win 7 x64 has most favorable results.... but for how long? keeping in mind MS only support this old OS until early 2020. Still imo interesting to see however the question remains, does win7 perform better on older hardware such as is the case with this retro rig? or is it win10 is just overrated bloatware? because I have done no OS tweaking whatsoever with either of these OS. They were all installed 'out of the box' & completely patched up to today's date.

Next series of posts will be p95 FSB OC results & 3DMark + PCMark runs with OC cpu.

Very good results. I should do some of the same with my QX6850 so we can draw a comparison.
As for OS, I think there is a good bit of hardware out there that still runs Windows 7 better than Windows 10. Case in point, my Lenovo T61p has always done better video playback under Windows 7. For some reason, the hardware works best with the Windows 7 rendering. In any event, it's very possible you can find hardware that runs better on the older version.

As for OS tweaks, I would highly recommend classic shell if you are running Windows 10, in order to restore the start menu and search functionality. This is a very small but powerful freeware that allows you to maximize the OS potential and if you really hate the metro look, as I do, it's a mandatory upgrade. In addition, I like to restore the quick launch folder and run a style similar to what you might find on Windows Vista or Windows 7. Is Windows 10 better? Absolutely it is, and for most rigs it's the best you can get. Plus, with a little tweaking you can make it run light, lean and mean.

With overclocked QX6850 you will burn your "P4" 4-pin connector.
Better be carefull.

@AlwaysHope Pretty good for a wimp like Q8400

Thanks, yeah I know what you mean about OS optimizations.
Did a lot of that back in the days of XP, Vista & Win7... but I'm over that kind of tweaking, I just use off the shelf stuff & suck it up... lol... default everything except maybe some privacy settings but that's about it.
I think that way it's more relatable to the average windows PC user today when shown OC results.

Lol. DDR3, GTX 1080i & M.2 drive.... off course mega points in productivity suite like PCMark08!
But yeah, its interesting to see cache crippled Q8400 in comparison. Our scores are practically identical. What's with the casual gaming scores? how come 2012 HD7870 GHz OC edition beats the mighty GTX 1080i???? me thinks software mucking up here...

Had trouble opening 2nd link, kept defaulting to your PCMark08

Cheers, but you sure about DX12 on HD 7800 series?
AMD don't agree > https://www.amd.com/en-us/products/graphics/desktop/7000/7800#

 

[agent_x007]

I am pretty sure about that DirectX 12 : LINK
Basicly : Everything, above HD 7730 (including it), has DitectX 12 support.

I see that but it's contradictory to the link I supplied. Who's the confused one here? AMD! because DX 11.2 is NOT DX 12.

 

[agent_x007]

Since Time Spy works on your card... I think my link is correct

Time Spy was meant to work with Windows 10 only, the 7 series cards came out when W7 was prevalent.
Edit, after a quick read up on Time Spy it is a Dx 12 test, my bad.
