Rockin some 1m, 8m, and PIFAST with Hipro-tech DDR MAXI

[k|ngp|n]

Hipro your Maxi is the man , nice clean stable power for vdimm throughout whole voltage range. Can't say how impressed I am with this thing. You are a jedi knight bro .
I couldn't wait for the ddr2 pcb to test it out, so I removed the choke coils on some mobos,and went ahead and soldered right to location in circuit with dimm slots, and it worked like a charm . Now tested on both am2 and lga775 with sucess.
This is the coil to remove on the p5wdh if you want DDR2 compatability and don't have the ddr2 pcb:


AND here are some pics of the DDR MAXIMIZER. The camera I used doesn't do it justice:




Shot of the air config setup rocking at 2.8v+ vdimm with p5wdh, 6800xe, 2gig CORSAIR 6400C3, SILVERSTONE 850W ZEUS PSU, and ATI 9200se pci vga...See, I'm not just an NV whore :


So nothing major, just some 1m and 8m,really pushing the memory mostly on the air/chilled air runs as too rule out other factors such as NB and cpu speed in testing the MAXI's effectiveness. NO special OS tweaks used. This b1 I have been using can only do about 3700-3900on air but it really depends on the cooler(between stock and mini-typhoon) I use and the temp of the air. Nice cold AC ducted near the cpu makes a nice difference. I pushed the cpu harder with ln2 on last benches. Anyways, testing is going great and it for sure rocks on the p5wdh and here are some highlights from that testing:

1M air 491mhz ddr on CORSAIR 6400 C3:

hexus PIFAST


This maxi is my new favorite weapon in the overclocking arsenal.
I really like the fact that I can solder it in for other things than just vdimm George. Would I be able to run both of gtX VGA mems with one MAXI??

[EZClock]

Very nice results. I will consiter picking one of these up .. especially w/ these Teamgroups .. begging for voltage .

[zbogorgon]

k|ngp|n
is it even possible to disable one core on p5wdh ?

I have done it through windows boot.ini. I did it here on this max screenshot
at 5507mhz:

I had another one at 5536mhz, but it whodini'd on me when I went to retrieve it from the hard drive later. Probably crashed before it actually saved the file, it was close

[dinos22]

that's excellent KP

can you run those sticks at max 4-4-4-8 timings under LN2 with upper divider. i reckon it will be faster than 3-3-3-x at mid-400 as those particular sticks have no issues past 600MHz with that vdimm i'm sure

[corvus_corax]

Very nice results. 491Mhz 3-3-3 looks great! I'd like to pick one

BTW, i like that skull

[VictorWang]

491mhz 3-3-3-8 pi_1m on P5WDH , insane !
still, conroe preffers higher ramclk but not good timings

my x6800 @ 360*10 , with ram=1080 4-4-3-1, pi_1m=14.047sec
I've compared a lot ram, d9dqt, d9gkx, d9gmh, 512m vs 1g...etc.
ddr2_1000 4-3-2-8>4-4-3-8>ddr2_900 3-3-3-8
ddr2_1050 4-4-3-8=ddr2_1000 4-3-2-8

Kingpin you got fantastic ram, so I think you can try ddr2_1200 4-4-3-1 (I bet you can achieve that with this pair of 6400c3 ).
3.6G pi_1m break 14sec with ease

interesting, care to share the secret

p.s.
is that it?

Hey Vic,
yah they seem like a pretty nice set so far. I got some c5's too, but these are better .. and thanx for all that info. I think I will try lots of diff combos now for some 2d action on air, really see what these sticks are capable of, now that I know I have some good clean unlimited voltage. I was doing some nice runs around ddr580 with 4-4-3-5 on DFI AM2/asus m2nsli with them and it did seem quicker than LL runs, but that was am2 so not entirely the same situation.

great results you did and hipro5's ram_maxm.
maybe ddr2_1300 era will come

[afireinside]

Nice results Vince! 491 3-3-3-5 is killer! To bad low lat is slow You really need to try 4-4-3-5 on ln2 with CPU 400*13=5200 and ram 2:3 @ ddr1200

[hipro5]

Ha, ha, ha......That's why I'm missing one of my "Blue" Maxies when counting them down!.....I've send it to some one of you by mistake and it was you who got it!.......All the others are the "Red" ones......You lucky guy.....

Nice to see that you're doing well with the DDR Maximizer Vince......
One question: How did this CPU do on default heatsink and max VCore you could feed it?.....

[ferds]

insane results!

[Nosfer@tu]

MEEEE NEEED

So when DDR2 is added we can use it whithout modding???

WHERE CAN I ORDER ???

[hipro5]

Depents on what mobo will you use......Some need to unsolder a coil like k|ngp|n did and then plug the DDR2 PCB into a DDR2 slot......

[erwinz]

nice OC k|ngp|n

[massman]

Great work K|ngp|n AND Hipro

[blind_ripper]

nice hipro toy ;
great benches KP

[Gautam]

Heh, nice to see hipro's and k|ngp|n's work come together rather than clash.

One rather off topic question/comment if I may. We've been seeing plenty of Pi action in the 5.3+ range from you and others, but 3D speeds appear to drop dramatically on LN2 (even DI it seems). On air and SS I've seen way wider ranges of stability than I'm used to, but this is looking even more drastic. You ran at 5.3 flat for 1M, but dropped nearly 200MHz for 8M and a hair further for 3D. On air and SS the gap is more like 80MHz or so...seems like something is falling apart at extremely low temperatures?

Stunning results nonetheless, and a stunning product by hipro.

You basically said exactly how it is Gautam. There seems to be quite a range on this chip between what is say SS,1m,8m,3d01,or 3d03 stable(requires highest level of stability out of any other benchmark IMO).
Maybe Hipro can make a mod to fix that . This holds true for ALL levels of cooling. Air, water, chilled water, DI, and ln2. To be honest 16m seems to require around same level of stability as 8m and I dont mess with 32m at all..ever. For sure the overclockability of the chip has alot do with how well it scales at diff loads. I'll try some others hopefully soon. I am not complaing, as I never dreamed I would be running 3d at nearly 5200mhz when these chips were first previewed some time ago. I am blown away with what INTEL did hear. I guess they were paying attention when the dothans were tearing up the FX57's on the orb. I can actually 8m this chip with the 12x at around mid 5200mhz on the chip, but this 2min 7sec 8m score at nearly 5100mhz is better IMO because it's all ram speed pulling it.
Tweaked like the SP pro's do, I bet could even challenge for WR.
Really just showing what the maxi can do with the ram so far LL and high volts. I don't have most of my highest 3d scores posted, so 3d speed on this chip is better than it may seem . With Athlons, 1m/pifast/8m/01 stability in addition to 05,06, and 03 stability in that order of difficulty, was more linear at all levels of cooling. But then again, with cold bug we weren't ever able to push those chips to the "edge" like we are doing with these where the stabiliy wheres thin on the top end depending on load.

Ha, ha, ha......That's why I'm missing one of my "Blue" Maxies when counting them down!.....I've send it to some one of you by mistake and it was you who got it!.......All the others are the "Red" ones......You lucky guy.....

Don't forget about my engraved name plate George . I'll do some more testing with p5wdh and let you know. I have a p5b here to test it on as well.
You guys will still want the ddr2pcb of course, as it's a pain sometimess to desolder coils off of mobo's and it could void the mob warranty lol . Still nice to know that it works without it.

@zbogorgon-- numproc =1 worked for me.

[Gautam]

Yeah, this ram speed effect sure is hard to get used to. Perfect for our purposes otherwise though.

You hiding your aces is what I'd have expected anyways.

If you think you can "challenge" the WR, I'm sure you can smash it. Would be nice to see some overall Pi WR's come back to the US...and even nicer to see em come to our neck of the woods.

[bachus_anonym]

Nice Vince! Maximizer really makes that 6400C3 shine! But pleeeaseee, try CAS4 clocks With this voltage at your disposal you should be able to give a shot at 1300 8-4-4-4.0, seriously Although, I'm kind of doubt, P5W is able to clock RAM this high... I don't even want to start imagining what that kind of bandwidth would do for 8M or Pifast at 5.15-5.20GHz
Grats again on a nice 491MHz

[Nosfer@tu]

I also have the Asus P5wd DX
But if I have the DDR2pcb I will not have to mod I understand?

Vic...you sure know your ram buddy
Ran some quick 1m and 8m at 4-4-3-1 and 14sec 1m on the nose ddr2 1080 w/ around 2.6v or so on maxi:
1m


8m


Using stock intel pentiumD cooler + default vcore only can get me to approx 3.6ghz George.
With 1.4-1.45vcore aprox 3.7ghz with stock cooler:


Anything over 3.7ghz with stock cooler + no AC, 1.45vcore+ and I was seeing temps in bios at 64-67c.
Backing off on the cpu and fsb a little, only pushing the ram 4-4-3-1 and ddr570 wasn't too hard for 1m at those timings around 2.66 vdimm on the maxi:


I really want to throw my c5's on the maxi now, too see how they compare with c3 and higher lats. On AM2, they did better at cas4. Also would like to start benching with the p5b. Have you tested the coil mod w/out ddr2pcb on that one yet George?

[dinos22]

FINALLY someone tests high RAM speeds at 4-4-3-x.....i want to see sub-10m 32M next
