bigboss Posted May 12, 2006 Share Posted May 12, 2006 That is impressive... WOW! I know that Dell's XPS renegade (with 4 7900GTs) had a Dual Core Intel @ 4.51 GHz.. I would definitely try building a rig like this. The only thing I've noticed with the guide is that it isnt very clear on the memory you should use in a rig like this. Not all memory can be overclocked to such a level and, you might not be able to get 4-4-4-8 on most chips but if Tom's hardware posts exactly what RAM they used, I might just build a rig lol Link to comment https://www.insanelymac.com/forum/topic/17328-a-41-ghz-dual-core-at-130-can-it-be-true/#findComment-111872 Share on other sites More sharing options...
Dee S. 73 Posted May 13, 2006 Share Posted May 13, 2006 Pentium D 805 on a Asus P5LD2-V since 1 week now, prime stable @ 3,6 Ghz (180*20) with ram @600Mhz, now clocked @3,5Ghz (175*20) with ram 1:1 ratio (700)Mhz since 3 days , no crash on osx , 1 crash in XP64 during a 3dmark but looks like xp64 faults... stock voltage and stock cooling... crashes @3,8Ghz(190*20) while boots but crashes while loading the os @4,0 Ghz but looks like with a good cooling and a bit of overvolt they could hit 4 Ghz no probs Lovely procs btw, remind me of the old Celly 366A ( the dual 550 capable ones) i had in my Bp6 , back in days.... Def. a good buy but watch out for new D9xx low cost ones, they should hit the streets in 2 weeks and looks like they 'll be worth the money too.... btw, i have a sandra SR3 cpu score of 19968.. not bad for a 140€ cpu stock cooling /voltage.. Just my 2 cents DS_73 Link to comment https://www.insanelymac.com/forum/topic/17328-a-41-ghz-dual-core-at-130-can-it-be-true/#findComment-111910 Share on other sites More sharing options...
Wayland Posted May 13, 2006 Author Share Posted May 13, 2006 Seriously, there is something to all that. Great to see it being able to go that far!!! I have a 940... any ideas how high that can go?

bofors Posted May 13, 2006 Share Posted May 13, 2006 stock voltage and stock cooling... Do you intend to stick with stock cooling? Does anyone here have any experience with liquid CPU cooling? I am looking at the CoolMaster Mini Aquagate 120 for about $90: http://www.newegg.com/Product/Product.asp?...N82E16835103165 I am wondering if liquid cooling is really worth the expense and hassle versus just going with something like that ZALMAN CNPS9500 for $60: http://www.newegg.com/Product/Product.asp?...N82E16835118223 Def. a good buy but watch out for new D9xx low cost ones, they should hit the streets in 2 weeks and looks like they 'll be worth the money too.... So you think something like the 920 will have good overclock potential? Are you anticipating something like a 905? I think overclocking Woodcrest might make a lot of sense (economically), as we will be able to buy the 1.6 GHz Woodcrest (Xeon 5110) for $230 while the 3 GHz model (Xeon 5160) will be freakin $850: http://www.theinquirer.net/?article=29510 Should we expect Asus to make dual socket Woodcrest boards with overclocking features? To what extent should it be possible to overclock the 1.6 GHz Woodcrest?

I've never seen such a difference between the lowest clock and the highest one. That is sweet though. I'd definitely grab a 1.6 and crank it all the way up to 3.0 GHz (and beyond ).. The only thing is that the 3 GHz model probably has a lower power consumption than the 1.6 which has been overclocked.. not a biggie though Link to comment https://www.insanelymac.com/forum/topic/17328-a-41-ghz-dual-core-at-130-can-it-be-true/#findComment-112213 Share on other sites More sharing options...
bofors Posted May 13, 2006 Share Posted May 13, 2006 I'd definitely grab a 1.6 and crank it all the way up to 3.0 GHz (and beyond)... Well I am going to grab at least two, Xeons seem to make the most sense for dual socket systems. .. lower power consumption.. Since Woodcrest is supposed to have radical lower power consumption, I am wondering if air cooling will be good enough for overclocking here. I don't something like the Zalman CNPS9500 will work for dual Xeons, it is just way to big. There Verax X20's look nice, but at $99 each they are a little too expensive: http://store.orbitmicro.com/commerce/catal...roduct_id=38506 Link to comment https://www.insanelymac.com/forum/topic/17328-a-41-ghz-dual-core-at-130-can-it-be-true/#findComment-112230 Share on other sites More sharing options...

And it's only $130!!!!! WOW! to answer your question "can it be true": i am not sure...i tried it, i own a asus p5ld2-vm and i couldn't get past 156 fsb (= 3.12 ghz), or it would say something like "overclocking or voltage failed" (i already put the pci express to 118, since it is a known weird problem) maybe it's because i have crappy ram, i have corsair value select 667, pc5300 or something like that but if anyone knows how i can get up really high (like fsb 180), i would be glad to know - even though i guess its the ram. simon Link to comment https://www.insanelymac.com/forum/topic/17328-a-41-ghz-dual-core-at-130-can-it-be-true/#findComment-112517 Share on other sites More sharing options...

As for the memory issues, forget that....the 805 is a great o/c'er cause it has a high multi (20x) and a low stock fsb , so even when clocked @ 4,0 Ghz , the fsb is @ a normal 200 mhz, any DDR2 ramstick must be able to reach it...( btw, to be sure i got some Infineon sticks ) @ Bofors : i'm planning to get a "BlueOrbII" , mostly to lower fan speed when @ 100% cpu...@3,6Ghz, D805 tend to be really hot ... (> than 68 C° after a sandra cpubench and 58 when idle..) btw, when high-clocked the 805 really pumps , knocking quite all the p4/Amd family but the XE... as soon as i'll get a "real" cooler i'll start pushing this "bad boy" to the limits as my own 805 stck voltage is lower than TomsHardware one so , it should overclock better.... As for now, i'm forced to stick @ 3,6 or 3,5Ghz .....

simisimisimi Posted May 14, 2006 Share Posted May 14, 2006 hello schneider, do you have any idea then why i cant go past a fsb of 157? currently i am even at 156, i had to go down because with 157, the graphics and also the system crashes. do you have any idea why i can't go higher? should i mess with the voltage? or with ram timings? or also, should i set some ram-setting in the bios, which is at "auto" right now? thanks simon Link to comment https://www.insanelymac.com/forum/topic/17328-a-41-ghz-dual-core-at-130-can-it-be-true/#findComment-112563 Share on other sites More sharing options...
Dee S. 73 Posted May 14, 2006 Share Posted May 14, 2006 What about the PSU ? If the psu is not the issue, that means u have one of the "bad " p5ld2-vm.. a few users reported problems in o/c with p5ld2-vm, thats why i decided to pay 30$ more and get the -V one.... my D805 is like the old cellys... i sticked it in , booted @ stock voltage once, set fsb to 200, everything else on "Auto" , it booted but couldnt go past osx install dvd boot phase;back to Bios and set it to 166 , booted perfectly and loaded osx installer, installed it, rebooted, -->bios again, fsb to 180 , os booted ok and didnt crash while installing a few progs (ilife,logic ,live,fcp suite), done... now, the best config for me is 175 fsb CPU, 700mhz Ram (spd Auto config latency )- 118mhz pciX, auto voltage for cpu,ram,chipset. 56 C° idle --> 68-69 C° during a 3d bench..

simisimisimi Posted May 14, 2006 Share Posted May 14, 2006 hello schneider, thanks for your info. but could you go a little bit deeper in this "700 mhz ram (spd auto config latency)" thing? i think i got that on "auto", should i change it? depending on the fsb i use, it "proposes" 3 different values. and why could be a problem with the psu? simon Link to comment https://www.insanelymac.com/forum/topic/17328-a-41-ghz-dual-core-at-130-can-it-be-true/#findComment-112660 Share on other sites More sharing options...

Take a look again at the article and the compatible motherboards that will work. They are noted to be 955 and 975 chipsets... They are easily twice the cost of your motherboard, and that's due to the huge amount of extras on there. I should sell my DFi SLi D / 7800GT and X2 3800 and get a Pentium D 805 setup, i cant see this A64 Dual Core Stutter getting fixed and i should gain from the Pentiums Superiour Encoding Performance.. Pentiums look to be more compatible with the OSX items for obvious reasons. Will Mac go AMD? probley not...

quagmire Posted May 15, 2006 Share Posted May 15, 2006 Does anyone here have any experience with liquid CPU cooling? I am looking at the CoolMaster Mini Aquagate 120 for about $90: http://www.newegg.com/Product/Product.asp?...N82E16835103165 I am wondering if liquid cooling is really worth the expense and hassle versus just going with something like that ZALMAN CNPS9500 for $60: http://www.newegg.com/Product/Product.asp?...N82E16835118223 bofors, I've had water cooling for a little over 2 years in my p4 3.0 ghz windows system. It was a thermaltake aquarius system. Just last week it took a {censored} (literally) in the bottom of my case, the whole pump cracked (I think the plastic just got really brittle). It was a pain in the ass to install/uninstall. I replaced it with a ZALMAN CNPS9500 and after running it through a few heat up/cool down cycles to break in the thermal compound [arctic silver btw] I found that the Zalman fan actually cooled the CPU better than the water cooling (32C @idle with w/c and 29C w/zalman - and that was almost immediate, i'm sure it will go down a little further afer a few more cycles). I've been beating my head against the wall for not going with something like the Zalman sooner. The inside of my case looks so much better w/o all those messy looking water tubes running everywhere and at night the Zalman fan looks like a jet turbine... its pretty cool.

bofors Posted May 15, 2006 Share Posted May 15, 2006 @quagmire - Thanks for sharing your personal experience. It supports my impressions of liquid cooling at the moment: (1) Too expensive. (2) Much more difficult to install. (3) Risky, due to potential leaks and pump failure. (4) Not significantly more effective than air cooling (expect perhaps in some extreme situations).

quagmire Posted May 15, 2006 Share Posted May 15, 2006 yea... I think if you really wanna go crazy with cooling you should just build your computer inside of a minifridge or somethin . haha.. yea cost is DEFINATELY a turn off for water cooling, my thermaltake system cost $100 more than the Zalman fan and the fan looks so much cooler (and of course cools better).
