Pros: fast stable cool running. what more could you want? these chips must be binned (hand picked) to get this kind of speed on that amount of voltage. ether way im not complaining. :)

Cons: price.... :(

Overall Review: been building PCs for a long time now and i can easily say this is the best DDR2 i have run. plugged in, set to factory specs in the Bios "1100mhz (5-5-5-15) @ 1.8v". ran Intel burn max stress 10 passes with no errors and they barely got warm! i may go for higher mhz later but for right now paired with my 780i and Q9550 @ 3.825Ghz not much reason to. if your trying to get the most out of your 780i, this IS your RAM... linked and synced you would be good all the way up to AT LEAST 4.675ghz before even having to OC the RAM.

Pros: I installed then went straight to setup. I set ram voltage to 1.84 and ram speed to 1200, 5-5-5-15. Booted to windows in a snap. They fit under my CORSAIR CMXAF1 Fans!

Cons: None I can see yet.

Overall Review: G.Skill has become my brand of choice. I owned almost every major brand of ram and G.Skill so far has always exceeded my expectations. Highly recommended.

Pros: I bought this kit to replace my G.Skill HZ modules that finally died. I have them running at 1141MHz at only 1.94v fully stable! The timings that were recognized by the BIOS are actually a bit tighter than my old HZ's (in regards to the 2nd and 3rd sets of timings in my BIOS). To get my HZ's to 1081MHz I had to use 2.3v and manually tweak the 2nd and 3rd sets of timings. This kit is probably the best replacement I could have found for my HZ's and the price is awesome for the performance.

Cons: Absolutely NONE!

Overall Review: I had originally picked up the PI kit that runs at 1066 and they were lousy. I couldnt get them to POST at 1081MHz using much higher voltage. Honestly, spring for this kit and you will not be disappointed.

Pros: This stuff is top notch DDR2, the best 4gb kit on the market right now. My kit is stable at 1133mhz and 1.9v. If I had a divider for my current OC then I am sure I could hit the 1150mhz-1200mhz range with 100% stability. If you are familiar with recent ASUS bios's then I am also currently running 1133mhz 1.96v at 5-5-5-15 trfc 55; Static read control enabled, MemOC charger enabled, PL8 and AI clock twister on Strong. I have not got Performance level 7 to pass but have not tried with a light clock twister yet. I used to own the PC28000 set and this stuff is 100x better To the guy below that said he could tell no difference, you obviously don't know how to overclock or tweak you kits because as far as overclocking goes this kit does more then any non PI series or PC8000 ever could. Worth the $140 I paid for them. Runs on lower voltages then any other DDR2 kit I have seen above PC26400

Cons: None, really NONE !!!!

Overall Review: My rig: Q6700 G0 3.4ghz; ASUS P5Q Deluxe bios 1103; G-Skill F2-8800CL5D-4GBPI 1133mhz; Sapphire HD 3970; Barracude ES.2 250gb 32mb cash 7200prm; Zalman 750w PSU; NZXT Tempest; Zalman 9700.

Pros: Follow-up to my initial 7/6/2008 9:35:24 AM review: After having some time with this RAM, I'm currently running @ 1120/5-5-5-15/1.925v with no probs. Have done higher speeds but 1120 is 24/7 use. Hits Performance Level 6 in Memset, Prime95 no issues...blah, blah. Not bad for 2x2GB DDR2!

Cons: None yet.

Overall Review: E8400, abit IP-35 Pro/BIOS 16, Visiontek HD4870/512, Enermax Infiniti 720, Win x64 Pro, etc.

Pros: Works great at advertised speed and voltage. Heatspreader looks cool. Overclocks up to ~1170 mhz without a hitch.

Cons: My set required 2.32 volts to be stable at 1200 mhz.

Overall Review: I was really excited about this RAM because of all the reviews on here that said it could do 1200 mhz with under 2.0 volts. I got it up to ~1170 mhz without going over 1.9 volts, but getting that last 30 mhz out of it took more voltage than i would have liked. I was testing stability with 1 pass of memtest86+ v4.20. It should also be noted that my motherboard (ASUS Maximus Formula) overvolts RAM pretty heavily, so while the voltage is set to 2.32 in the BIOS for 1200 mhz, the RAM is actually getting about 2.45 volts. I guess I'll keep these settings and see how long the RAM lasts... this will be the real test : )

Pros: Worked at specification almost from first boot on a Maximus II Formula MB. Running at 1112 with a quick selection in BIOS, at 1.95 V. (just to be safe). RAM sinks are relatively cool to the touch, and passed Memtest with flying colors. Booted and loaded Windows Vista 64 with both sticks installed, and NO issues. (BIOS 2104)

Cons: The tall sinks may interfere with some CPU heatsink designs, but was not an issue for me.

Overall Review: I have not tried to overclock these yet, but I am going to try for 1200 at above 2.0 V. This is my third set of G.Skill RAM now, and have yet to have any issues with this RAM. I will continue to buy G.Skill for future builds.

Pros: for the money, you cant beat it!

Cons: heat sink it tall so it can cause problems with your cpu heat sink if its over sized.

Overall Review: my mobo is rated for ddr-800 but i dropped these in and right now i have DDR-832 "BUT" my timings are 4-4-4-12 which i guess is an equivalent to about DDR-1080 at CL5
