Ram compatiblity in OC
Ram compatiblity in OC
first of all, i know its old hw, so i think it should be well known here:
its an older architecture i want to build, so i guess it s good known here
i want to use as platform (mobo) the p9x79 deluxe in combination with the 4930k (to ensure the pci-e 3.0 compatibility), no question about that.
my problems are the rams, cause i want to use the full possible performance in timings and speed with the max of capacity (64 gb)
as the used market gives all that parts to a good price available.
my plan is to use the F3-2400C10D-16GTX TridentX from GSkill
all identical rams for sure 8x8 gb at 2400 mhz OC with the recommend timings from the producer DDR3-2400MHz CL10-12-12 @ 1.65V
-> 2 x Quad Channel
i read so many different opinions and problems in the net, especially when i want to go to the capacity and oc boarders.
What do u think about my chances to get that stable running, with the given components?
or would u recommend me more the equivalents from GSkill:
RipjawsZ or RipjawsX
witch all has the same specs, at least about timings and mhz. and btw, i really wonder, why GSkill is producing so different Rams with equal specs. what i found out already, is that it has to do with the chipset and sandy/ivy bridge variation recommendations from GSkill, and exactly that is what confused me so much.
for every help or experience sharing, i would be very thankful.
nice greetings from germany

Welcome to the forums!
Both kits will be identical, as they only differ in a heat spreader or a colored sticker on top. I recommend against investing in older hardware, especially since the cost of DDR3 is significantly higher than DDR4, where speeds are much better for the same price.
Thanks for the quick response from Lutfij Primary, it seems the choice between RipjawsZ, RipjawsX and TridentX doesn’t really matter much, right? What are your thoughts on this after reading what I found online about platform recommendations? Do you think it’s just a small difference?
For your second point, sorry for the misunderstanding earlier. In reality, many people make the same mistake as others on the internet—ignoring the significantly higher latencies. It’s not even worth mentioning the price differences, because I can get these units in very good used conditions, which isn’t comparable to the current DDR4 options.
For example, comparing Ripjaws/TridentX DDR3-2400MHz CL10-12-12 with Ripjaws DDR4 SO-DIMM DDR4-2400MHz CL16-16-16 and even lower MHz RAM in DDR4—those higher-timed chips cost a lot more. Just to give you an idea: if you look at the required MHz to compensate for those faster timings, and compare the prices of similar 64GB units from the same series, it’s clear.
I don’t think fewer slots with larger capacitors and better timing will improve performance, even if they support higher MHz. My goal is to achieve much higher bandwidth plus dual quad channels with lower timings. That’s something I’d rather not debate further.
What I need to know is whether this configuration can run stably together. Are there any hardware restrictions, like full bank occupancy, maximum OC speed, or RAM timing limits that could affect it?
Any tips from other readers would be appreciated. Thanks in advance for your help.
DDR4 generally offers better performance compared to DDR3. You notice this because DDR4 supports speeds like 3600 C14 and 5200Mhz C18, which are significantly higher than any DDR3 module. The 3600 C14 is much faster than the 2400 C10. Their bandwidth in GB/s can be compared for a clearer understanding. Your CPU remains adequate for RAM, but running more than two DDR3 modules at 2400Mhz would likely cause issues. It probably won’t work, even if you opt for cheaper DDR3 options.
Thanks for your reply.
Again, I don’t want to go into that discussion about DDR4 being faster than DDR3 if you consider the right specifications... it’s not just about the RAM sticks, but also the CPU, memory size, and overall setup. It’s a budget issue, not only about the RAM. I really need 64 GB for my professional tasks. And once more: I don’t want to talk about that. Thanks for taking the time to consider and respect my position.
Now, let’s move on to your second point—please share your interesting observation.
Each motherboard and CPU varies, yet using eight modules isn't ideal because it strains the CPU. You should opt for something like a TR, Xeon or EPYC.
Basic recommendations:
Memory Specifications
Max Memory Size (depending on memory type) – 64 GB
Memory Types – DDR3 1333/1600/1866
Max # of Memory Channels – 4
Max Memory Bandwidth – 59.7 GB/s
I believe more than 4 channels could strain the CPU?
If I aim for 64 GB, that would require 4x16 GB, and at 1866 MHz, would the CPU still be able to process it, even in OC mode?
Do you have any experiences that can support this idea?
It supports up to 8 modules, though you'll need to reduce the RAM speed. It's unclear if a 1x16Gb DDR3 is available, but ensure your motherboard can accommodate 16Gb in a single slot.
Mh... what am I surprised by is my current setup:
Gigabyte GA-X58A-UD7 supports 3 channel DDR3 2100+ memory x2 with the Core i7-980.
Maximum storage size (depending on type) is 24 GB.
Storage types include DDR3 1066, and it has 3 channels.
I run it using KHX1600C9D3K3/12GX x2 (9-9-9-27) = 24gb @ 1600mhz.
Definitely, I had to overclock my CPU, and I know not all CPUs are equally compatible with different clocks.
Comparing the specs made me feel way beyond the basic advice.
It was a bit tense and stressful to find the right frequency, multiplier, and power settings, but now it runs smoothly at 3,84 GHz on six cores.
I’m planning a more modern build that’s better suited for higher clock speeds.
At first, you were correct—there are no 16GB DDR3 modules available. I also looked at your earlier comment: "you would need something like a TR, Xeon or EPYC." The EPYC is from AMD and won’t fit with the x79 chipset (Intel) on my board, even if it’s a different socket. TR isn’t familiar to me, but I checked the compatible Xeons for my socket. None of them match the performance you’re expecting from the 4930K, especially in terms of clock speed, supported RAM types, and maximum RAM speeds. Some are similar, but not significantly better. If it won’t work with the 4930K, I’m also unsure it will work with these options.
Thanks for sharing your thoughts—it’s really appreciated.
