wont the Q6600 have some issues having FSB 1066MHz and the board having 1333MHz, what will happen, it downclocks?
and if it does wont it bottleneck the combo of having q6600 and the giga mobo?
Quick question for other owners of this mobo. I'm finding its not controlling the speed of my cpu fan.
I have a Xigamatek S1284 with the bolt thru kit mounted on it.hmm thats not good. I'm wondering if the xigmatek s1283 bracket will fit with this mobo
Well I got my UD3P and started switching from my DS3L. After wrestling my Tuniq Tower off I worked on mounting it to the UD3P. The H-bracket didn't fit between the heatsinks. And one of the pins on my Intel heatsink isn't pushing all the way through. Frustrating.
Just a word of warning to Tuniq Tower owners.
So what are the main differences between the UD3P and the DS3R?
If I were to do a crossfire setup on this board would it be 16x+8x, or 8x+8x?
from newegg :
Expansion Slots
2 x PCI Express 2.0 x16
(one running at x16 model, another one running at x8 model)
The tweaktown review says differently though:
http://www.tweaktown.com/reviews/1626/4/gigabyte_ep45_ud3p_motherboard_exclusive_review/index.html
Lastly, we are onto expansion possibilities. Thanks to the P45 Express chipset we get true Crossfire. How this works, if you havent read any P45 reviews in the past, is the 16 lanes from the P45 Northbridge have two modes; single GPU and multi GPU. When in single GPU, all 16 lanes are routed to the blue PCIe x16 slot. When a second graphics card is inserted into the orange PCIe x16 slot, the board automatically steals eight lanes from the blue slot and sends them to the orange slot, giving both cards eight lanes of bandwidth each. One disadvantage to this setup is the fact you cant run two of ATIs X2 series cards in CrossfireX, since there isnt enough bandwidth, they just wont work.
Generally yes 1.8V is a good choice for RAM voltage. Higher voltage RAM do tend to offer higher speeds, better overclocks and/or tighter timings. However you seriously would not notice the difference between CAs4 and CAS5 in any real world app or game. So the CAS4 G.Skill RAM is NOT worth the extra $15 over the $50 CAS5 G.Skill RAM:
G.Skill F2-6400CL5D-4GBPQ 2 x 2GB DDR2 800 RAM - $50
1) Read above. Definitely the $50 G.Skill RAM
2) It is possible to overclock BUT your overclock will be limited due to the 80mm fans and stock HSF. As for max OC, YMMV but do keep these parameters in mind: Keep the Q6600 at around 65C under load and the voltage no higher than 1.5V. As long as those two parameters are met, your OC'd Q6600 will be fine. Though out of curiosity, what case do you have?
I read that review as well and I *think* (please correct me if I am wrong) that this means when 2 video cards are used, PCI-E(1) will work at 8x and PCI-E(2) will work at 8x as well.
I was also looking at the corsair:
Corsair:

That's correct. It's not a problem for 2 single GPU cards as they will each run at 8x 8x. According to Kyle from this site he does not think that bandwidth is an issue though with current gen cards and games. So 2 4870s or 2 4850s would work fine. I don't know why 2 4870x2 cards would not work well but I will take their word for it. I guess 4 GPU's saturate the bus.
If I were you I would get Corsair but this one
CORSAIR DOMINATOR 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500)

Not only is it on sale for $79 after rebate with free shipping, but it comes with a memory cooler. And one more thing. With Intel CPU's lower timings is not nearly as important as higher clock speeds. You will always want to choose higher clocks over lower timings if you can't have both at the same time, which you can't if you want to run at higher speeds. If you are running 1:1 though and can't change straps because its beyond the capability of your memory and you have some headroom, then its good to try and lower timings, but only at that point.
YMMV = Your Mileage May VaryOkay, I figured there would be a limiting factor so I just wanted to know. It seems everyone is oc'ing now-a-days. It's become common place. Even the mobo's are designed to take advantage of this. Forgive my ignorance, but what does YMMV mean and how long will the OC'd Q6600 will be fine? What is the life expectancy of an OC'd chip/mobo/memory?
I kept reading faster, better timings so I was looking at CAS4 instead of 5. With that in mind, I was originally looking at the Kingston HyperX PC8500 Dual Channel memory at tiger. I heard they use Micron chips which are better (correct me if I am wrong). Would you recommend this over the G. Skill? I saw it at tiger and variations at new egg.

You would not notice a single difference between DDR2 800 and DDR2 1066 in everyday apps and games.Also, if I don't OC and use the Dominator, would I notice a difference in 800 vs 1066? I've read in various places that the difference is minimal.
The chipset voltage is the one called MCH Core. Depending on how much your overclocking you may want to lower your MCH reference by a notch or two and then stability test.I don't know what the chipset voltage setting is in this screen can anyone let me know? And besides that and vcore setting is there any other setting on this screen I should tweak for when I'm overclocking? Memory is already stable, I'm done with that.
Great. Thanks for the info. I saw your earlier post about this stick of ram but I was not sure if my mobo would take it due to the higher voltage requirement. Question: Whats the advantage/disadvantage of higher/lower voltages when dealing with memory? GA recommends 1.8v on this board but obviously you can increase it. Does higher voltage mean more power which translates into higher clocking/better performance? Also, if I don't OC and use the Dominator, would I notice a difference in 800 vs 1066? I've read in various places that the difference is minimal. I am just wondering, I love computer knowledge. I eat this stuff up

What speed can I expect when OC'ing the Q6600 (with stock options and my 3 80mm fans; 2 under the PS and 1 adjacent the CPU and stock heatsink)?
I already answered this question when I said "YMMV" In other words, pretty much a matter of luck. But I wouldn't be surprised if you could only get around 2.6GHz to 3.0Ghz.
