Asus P5KC (hybrid DDR2/3 mboard) + CORSAIR 4GB 1600MHz DDR3 + 2GB PC10K DDR2 test

[dinos22]

hey guys

i got some DDR3 ram for testing and thought i'd pair it up with an entry level asus P5KC board for initial tests

i didn't see too many people test this board and certainly no 4GB kits heheheh w00t they are sexy beasts



TEST SETUP

• Asus P5KC Motherboard >> updated to latest 0701 bios
• 4GB kit Corsair 1600MHz 7-7-7-20 DDR3 RAM
• 2GB kit Corsair 1250MHz 5-5-5-18 DDR2 RAM
• Intel Core 2 Duo E6700 L626Bxxx CPU
• Intel Core 2 Quad Q6600 L727Axxx CPU
• PCI nvidia MX400 GFX card
• Thermaltake Big Typhoon + 100CFM Panaflo fan
• 60GB IDE MAxtor HDD
• 620W Corsair HX620 PSU
• Windows 2003 Server 32-bit

CRAZY HOT area >>> i burnt my finger on this son of a



VDIMM MEASUREMENT POINT



Here is the RAM









did some tests with Asus P5KC

board had a lot of quirks that's for sure but i managed to squeeze a bit out of it anyways

for some reason the board was booting at 1T command rate lol and there is no option in bios to change it

btw vdimm measured with multimetre 1.9v in bios = 1.88v load >>> 2v in bios 1.98v idle load in windows
ram didn't seem to respond to higher voltage but i think this is the board limitation and not ram... as i've seen it go higher on blitz















no tweaks besides largesyscache >> on std server 2003install

i didn't even notice the last shot was on performance level 9 TIME is still pretty good lol

anyways that's as far as i got atm


RAM & board notes:
with a bit of tweaking of subtimings and actually run some Spi tweaks i would say around 900 7-6-5-20 would be about the same as 600 4-4-4-x

2GB kits should do that with eyes closed but 4GB kit may be harder

i must say testing all these boards leads me to believe that DDR3 boards leave a lot to be desired and need work on bioses....blitz is the best at the moment though >> shame i couldn't have mine for longer than an hour and i certainly wouldn't go buying this board with the pricepoint it will be at EEEEEEK


in terms of Asus P5KC i don't know about u fellas but i took some photos of the phase coil that burnt my finger idling....sitting next to the 4-pin connector

i would definitely not buy this board unless i have a sample

and also my P5KC droops bad

I tested a quad core first and jacked it up to 3.6GHz with 1.42v idle but after about 10 seconds the vcore just starts dropping bad and reboots the machine. I thought it may be too much load from the quad CPU and stuck my E6700 CPU in there >>>>>>>>> 1.36 in bios, 1.336 idle windows and under prime it keeps dropping to 1.31/1.29/1.27/1.26/1.25/1.24 i gave it a couple of strokes where pencil mod is supposed to be NOTHING

so it seems that it ain't the quad core load afterall but just voltage regulation on the board

i must say after testing that other value board and finding out how impressive it was i am pretty disappointed in this one particularly with how badly hot that area was and droop issues even with a quick pencil mod which made no difference. I was expecting the bios to be a bit more problematic because it is a hybrid board but geez i couldn't even post my PC10000 sticks past 550 WTF :wired: and i am really surprised i even managed what i did with DDR3 >>>>>>I didn't check but i think the maxing out of DDR2 might have had something to do with bios setting 1T command rate at default........some more investigating is necessary

lol i really should get memset 3.3 beta2 for command rate as well
