**Official ABIT IP-35 Pro Review/Overclock/Guide Thread**

[Algeriano]

I honestly dont have a clue.... Its my benching rig so Im always testing for something else and most of my voltages are probably too much....

ok thank you
to finish, you would advise it Gigabyte P35 DS4 or abit IP35Pro ?

[Ace-a-Rue]

yea, In re to one of your recent posts Ace, Didn't think about it until now but, the performance gain I got with the b4 bios was the first time I flashed using your procedure, b3 was flashed using abits flash menu. that is most likely where I got the performance gain as others have not seen a difference. Either way, Thanks Ace for the good info.

anytime!...glad to give a little back since i've learn so much cruising around in the forum!

Just acquired a pair of 512 x 2 Kingston DDR2 800 ValueRAM part number KVR800D2N5K2/1G. Managed to run them at 604MHz with 2.1Vdimm and 5-5-5-15-2T. There's a logo on the chip with six small squares in a 2 x 3 pattern and two lines surrounding this pattern. Anyone familiar with this logo? Sorry but no digital cam.

Those "N5" modules generally overclock well. Kits without N5 are normally binned at 430MHz.

[Ace-a-Rue]

it is very obvious that abit boards work better with kingston modules.

what processor do you have?

E4300 (L2 stepping with 100C Tjunction) at 3.56GHz with 1.505Vcore. Divider set at 1:1.50, 2.1Vdimm, 5-5-4-4-9-2T. Room temperature is 89F. Will run Orthos for 1 hour during the winter. No need to stress my CPU with high Vcore and temperature right now.

VTT, VNB, VSB at default.

have you pushed your RAM more

Got very strange problems when i try to open Uguru.
Installed my IP35 Pro yesterday and a new HD 2900XT. Today i updated bios to b04. Did a run in 3dmark2001 and got 47900p with cpu and gpu at stock.
Using the latest ATI driver to. What can be my problem u think ?

My system:
Abit IP35 Pro
E6600
Asus HD 2900XT
Xtreem PC6400 2gig
Xp Pro

Hope someone can help me

Look at the pic and u know what i mean ^^

[shawn1998]

That looks like some sort of video corruption to me, most likely something to do with your new video card. I've seen that when temps are too high with the video card, check the cooling on it maybe?

[Ace-a-Rue]

are you running in "dual" monitor scenario...my son had something similar and it was due to the driver running in the dual monitor mode...check that first...if that is not the problem, then uninstall the driver, reboot, and reinstall it again.

[ante_ante]

Running with only 1 monitor. And the temps for gpu are around 60-65 when just surfing. It seems only got problem when i open Uguru. Everything else works fine, can play without atrifacts. But´s hard for me to use uguru when i can´t see everything. When i open firefox the black box on the screen disappears.
Hmm really strange....

[sofarfrome]

You should also uninstall uguru and reinstall it, preferrably with the latest version which can be found in this thread.

no, no, no! ...he was running only one monitor but the driver through the control panel was set up to run in a dual monitor mode...as soon as he changed it to a single monitor mode, his video corruption went away...check your video driver configurations through the control panel.

[K.I.T.T.]

Has anyone got anything good to say about the IP-35 Vanilla? Nearly a £40 difference between it an the Pro. Would be nice if it OC'd well

[Ace-a-Rue]

i would go with the Pro because you have Uguru...that little prog is a jewel in my estimation...you can change any voltage, pcie freq or FSB from windows...it makes it so much easier on you when you are trying to find the right combination of voltages and FSB setting for your maximum overclock.

[furballi]

have you pushed your RAM more

I may bump up Vdimm if I know the mfr of these chips. Very strange logo. RAM is rated at 1.8V.

Just discovered a possible RAM anomaly with my Abit IP35-E/E4300 CPU combo. 1st pair of Kingston DDR2 800 (chips on both sides, 1GB x 2 with SPD 5-5-5-18/1.8V) is set at 5-4-4-9-2T in BIOS. Memory clock speed is 480MHz (overclocked CPU with 1:1.25 memory divider). Memtest 86+ V1.70 shows bandwidth of 5628MB/s.

Swapped these RAMs with 2nd pair of Kingston DDR2 800 (chips on one side, 512MB x 2 with SPD 5-5-5-18/1.8V). Same memory settings as the previous pair. Memtest 86+ V1.70 shows bandwidth of 5197MB/s.

Not sure why the speed of the 2nd pair (512 x 2) is lower than the first pair (1GB x 2) when all other parameters in BIOS are the same. Both pair are stable up to a minimum of 576MHz.

Memtest reports a bandwidth of 4358MB/s when all four sticks are added to the MB (dual channel...1+3, 2+4).

Went back to BIOS and manually set the RAM settings to 5-4-4-9-30-3-4-3-4 to remove any AUTO RAM dectection mode. Re-tested both pairs. Still no change with the bandwidth numbers. BTW, all sticks passed Memtest86+.

Booted to Windows to check the performance of the RAMs using Super Pi. The 1st pair (higher bandwidth per Memtest) yields marginally faster time.

Can a single-sided RAM module be slower than a dual-sided stick? Is the BIOS having issue with proper detection of the single-sided modules? Has anyone seen a similar drop in memory bandwidth with 4 sticks vs 2 sticks? I'm aware that adding more RAMs will place a higher load on the memory controller. That's why most rigs will drop from 1T to 2T with four modules in place.

It is identical to my IP35-E (about 488MHz FSB). IP35 adds 1394, heat pipe cooling, RAID, and two additionals SATA ports. IP35/IP35-E share the same BIOS.

my only guess is that you are using two disimilar stick sizes...one pair is a single sided and the other is double sided...the MCH probably is tweaked to handle the double sided over single sided memory sticks.

I also tested the single-sided sticks in dual channel without the double-sided modules on the board. I agree that the only explanation is the way the SB handle double vs single sided RAMs.

Does anyone encountered any drop in speed when moving from two sticks to four sticks?

[Neon Biker]

Yes, it's normal for sigle-sided to perform worse than double-sided RAM because of the bank interleave, but the perfromance drop should be minimal.

[paradigital]

Just shoved a cheapo E2140 in my IP35-PRO (its a stop-gap until the price-cuts), and decided to give it a little bit of a push, can probably go further than this, but seems to be stable so far




EDIT:

Got it further now, 3200MHz

[furballi]

Yes, it's normal for sigle-sided to perform worse than double-sided RAM because of the bank interleave, but the perfromance drop should be minimal.

I would also expect a small drop in speed with single-sided stick, but are these numbers valid in Memtest86?

MBENCH shows similar read/write speed under SSE. Read for INT and MMX are about the same. Write speed is 15% higher.

write speed should be better to a single sided row of memory chips...i would think with the single sided row stick you could lower your memory setting (make them tighter than the double sided) and in effect, get better or comparable read speed compared to the double sided.

It will be higher with higher density module. In my case, the dual-sided chip has twice the capacity of single-sided chip (same density). The single-sided chip can run at higher FSB speed. Do you have any recommendation for a free memory bench proggy to check these RAMs?

[Dami3n]

What are your pwm temps? in my board i think they are little high, always between 46-48º in idle, 56-57º in load .

[Ace-a-Rue]

for my board...i have 39-40C idle temps but i have 2 fans blowing on the heatsink over the PWM.
