G5 on the Test Bench :)

Well, after a long hiatus from testing, I finally got around to pulling the G5 out of my Green rig. I replace the G5 with a shiny new bowed and nozzled Fuzion :D I can tell you that I don't have high hopes for the G5 beating the GTX or the Fuzion but we will see. I also plan to test the new Enzotech block and the Thermalright block. I think I will have to purchase the Thermalright block but apparently Enzotech is sending me a sample so that is good. I have emailed Marci to send me his source excel file from which he made that awesome graph of all the blocks and each mount. This way I can continually add to it as blocks get tested :)

Anyhow, just a quick update. I'm back on the horse. :rolleyes:

how much does a nozzle really improve? ncix has them real cheap...i think i'm going to get one...:)

when does the enzotech arrive?

NCIX also won't have stock until the same time they arrive from everyone else...

YAY, I can finally see how my G5 compares to some modern-day blocks :D

Let me know if you need anything from a fellow G5 owner :)

Excellent news nik, looking forward to the test results. :up:

Will be intresting to know!

any updates?

Scott, I put the G7 in to the machinists for them to fix it, and that was 6 weeks ago. I've reminded them a few times, but they're not being good to me.

Curious to know how the G5 goes.

me too...:up:

Same...

Does that mean you're gonna test indie blocks as well as the big stuff? I have a reason for asking...

Sorry dudes, nothing yet, was my birthday today (well the 6th) and it has just been HOT here, too hot to test... perhaps tomorrow I can get a run or two in.

Happy birthday!!!

looks like we got the best month for birthdays...

yep..mines the 12th

20th.

I may have a surprise for everyone else though...

Hmm, another oddity. Just did first run of the G5 and it posted the WORST numbers yet - of ANY block :( . Something is amiss here. I did a quick remount, except i rotated the block 90 degrees so the inlet/outlet are vertical rather than horizontal. Seems to have made quite a difference although it was just a quick 'check and see'. I'm done for the day, I hope it is just a weird mount issue with caps on the board or something but the paste imprint looked good etc. Will know more next week.

huh, check you jets--mine get plugged about every month from miscellaneous junk that jets that gets dislodged. This is definitely just an issue with the G5 (or mine specifically), as the same loop (thoroughly cleaned out multiple times, and every time I change a piece of hardware) with my three past Swiftech G4's never ever ever got plugged.

Block was disassembled, checked and cleaned before put on test bed. Do you think I'm new? :D

I was of course joking...I like many XSers really appreciate all your time and effort on your excellent testing methods...

Thanks

Oh yea Happy Belated B-day

Niksubh I have to say that my temps with my G5 have not been very good. I would not be surprised if it didn't perform all that well here.

But no doubt it should spank the G4... not be worse??

I know you were joking! And thx2u2! wewtlarz!

The G5 is a great block with unsurpassed performance for its production time..it came out like 2yrs ago or so..cpu were very different..it has stood up well....
I bet the "bad temps" are 2C or so

Skin today's dualcores and I bet it spanks. Has to do with IHS well, spreading the heat. Gets outside the contact patch.

...or so I remember Cathar saying...

More than likely a caps clearance issue.

If you can't slide a piece of paper freely between ALL the caps and the stepped portion of the block base, then it's going to be a caps clearance issue.

I solved this myself by customising up a sturdy back-plate out of a spare G5 mounting plate and some thin MDF. Temperatures improved markedly.

One of the mods I'm having done to the G7 to send to Scott is a greater cap clearance.

I designed the stepping to clear the caps (for both G5 & G7), but with a high mounting pressure the board and even with back-plates flex enough that the clearances go to zero and the block starts to tilt on the CPU.

hahaha, I was only pointing out that in my experience, the jets on the G5 plug a lot more easily than the G4's.


Cathar: what kind of temp difference are we talking about between no back plate and a rigid backplate? Is it enough to spend some bucks and make one/buy an extra mounting plate, or are we talking 1-2c max?

Yep no doubt. Odd though I'm using the same model board as my board in the green rig. Rotating the block 90 degrees 'seems' to have fixed it, but havent had a chance to do a run yet.

Happy b-lted bday Nik, mine is in 6 days.....................oh god I will be.........30..........


I saw a G5 up for sale a little while ago here on XS, if I could I would pick it up.

Use it on my naked X6800 :D

Heads up to other owners............I ran into mounting issues on the EVGA 680i because of CAPs...........Cathar knows about that.:mad:

All it can take at times is for one of the caps to be sitting just 1/100" higher than another, and then it's a problem.

Also, depending on where the socket is in relation to the screws holding the board into the case, or even just due to the memory slots, boards will flex more in one direction than another under mounting pressures.

LOL, do you know how huge 1-2c would be? That'd be the difference between getting a G5 and getting a TDX. Well...probably close.


@Stew: I was on the waiting list for the G7's way back, I assume my block is in the mail also? :p:

any update nikhsub?


EnJoY-the difference between an Apogee and an Apogee GTX is about 1.5-2c (according to Nikh's own testing), making the difference between a TDX and G5 waaaay more than 2c (that's assuming the G5 is towards the top of the pile).

Sorry been very busy and then got sidetracked with stepped bases LOL. Anyway, I spoke to Stew at length last night, I am going to have the G5 stepped... It is a marked improvement no doubt, I guess we shall see how it does against the rest.

Scott,

If you want to write a review of the Thermalright block I can contact Thermalright for you. I have a good repore with the Thermalright PR guy.

I'm not great at reviews... but I would love to test the block... I have the revised enzotech block i need to test as well. Bruce said he has some 'revised' things for me too... gonna get busy again in my high paying WB testing job. ROFL.

Been having that problem with last gen and current gen Asus boards. Also the Intel Blackaxe. Caps are simply getting in the way, thats why my G5 is just sitting on the shelf right now. :(

Any chance the revisions include a stepped, silver base?

were you able to finish your testing?

Yes, but it won't include a NON stepped base... The G5 is still at the machinists shop, I need to pick it up but I have been very busy. I had it stepped because it won't compete otherwise.

ah, well it's good to know that at least unmodded, it's outta the game ;)
